We were founded on April 1, 2016. Corey Henry Peterson is the principal owner of Great Hill Advisory. As of December 31, 2025, GHA has $218,409,501 in discretionary AUM. Types of Advisory Services Comprehensive Financial Planning Upon engaging in this service for the development of a comprehensive plan, a Client will be taken through establishing their goals and values around money. They will be required to provide information to help complete the following areas of analysis: net worth, cash flow, insurance, credit scores/reports, employee benefits, retirement planning, insurance, investments, college planning, and estate planning. Once the Client's information is reviewed, their plan will be built and analyzed, and then the findings, analysis and potential changes to their current situation will be reviewed with the Client. Clients engaging in this service will receive a written or an electronic report, providing the Client with detailed financial information designed to achieve his or her stated financial goals and objectives. The plan and the Client's financial situation and goals will be monitored throughout the year and follow-up phone calls and emails will be made to the Client to confirm that any agreed-upon actionable steps have been carried out. On an annual basis, there will be a full review of this plan to ensure its accuracy and ongoing appropriateness. Any needed updates will be implemented at that time. In general, the financial plan will address any or all of the following areas of concern. The client and advisor will work together to select the specific areas to cover. These areas may include, but are not limited to, the following: ● Cash Flow and Debt Management: We will conduct a review of your income and expenses to determine your current cash flow and provide advice on prioritizing how any savings should be used or how to reduce expenses if needed. Advice may also be provided on which debts to pay off first based on factors such as the interest rate of the debt and any income tax ramifications. We may also recommend what we believe to be an appropriate cash reserve that should be considered for emergencies and other financial goals, along with a review of accounts (such as money market funds) for such reserves, plus strategies to save desired amounts. ● College Savings: Includes projecting the amount that will be needed to achieve college or other post-secondary education funding goals, along with advice on ways for you to save the 4  desired amount. Recommendations as to savings strategies are included, and, if needed, we will review your financial picture as it relates to eligibility for financial aid. ● Employee Benefits Optimization: We will provide review and analysis as to whether you, as an employee, are taking the maximum advantage possible of your employee benefits. If you are a business owner, we will consider and/or recommend the various benefit programs that can be structured to meet both business and personal retirement goals. ● Estate Planning: We will review your current estate planning documents and provide you with a summary. Our advice also typically includes ways for you to minimize or avoid future estate taxes by implementing appropriate estate planning strategies such as the use of applicable trusts. We always recommend that you consult with a qualified attorney when you initiate, update, or complete estate planning activities. We may provide you with contact information for attorneys who specialize in estate planning when you wish to hire an attorney for such purposes. From time-to-time, we will participate in meetings or phone calls between you and your attorney with your approval or request. ● Financial Goals: We will help clients identify financial goals and develop a plan to reach them. We will identify what you plan to accomplish, what resources you will need to make it happen, how much time you will need to reach the goal, and how much you should budget for your goal. ● Insurance: Review of existing policies to ensure proper coverage for life, health, disability, long-term care, liability, home and automobile. ● Investment Analysis: Based on your cash flow projections and risk tolerance we will develop an asset allocation strategy to meet your financial goals. We will review your current investment vehicles and strategies, including employer offered plans. We can also assist in establishing your own investment account at a selected broker/dealer or custodian. The strategies and types of investments we may recommend are further discussed in Item 8 of this brochure. ● Retirement Planning: Our retirement planning services typically include projections of your likelihood of achieving your financial goals, typically focusing on financial independence as the primary objective. For situations where projections show less than the desired results, we may make recommendations, including those that may impact the original projections by adjusting certain variables (i.e., working longer, saving more, spending less, taking more risk with investments). 5  If you are near retirement or already retired, advice may be given on appropriate distribution strategies to minimize the likelihood of running out of money or having to adversely alter spending during your retirement years. ● Risk Management: A risk management review includes an analysis of your exposure to major risks that could have a significant adverse impact on your financial picture, such as premature death, disability, property and casualty losses, or the need for long-term care planning. Advice may be provided on ways to minimize such risks and about weighing the costs of purchasing insurance versus the benefits of doing so and, likewise, the potential cost of not purchasing insurance (“self-insuring”). ● Tax Planning Strategies: Advice may include ways to minimize current and future income taxes as a part of your overall financial planning picture. For example, we may make recommendations on which type of account(s) or specific investments should be owned based in part on their “tax efficiency,” with consideration that there is always a possibility of future changes to federal, state or local tax laws and rates that may impact your situation. We recommend that you consult with a qualified tax professional before initiating any tax planning strategy, and we may provide you with contact information for accountants or attorneys who specialize in this area if you wish to hire someone for such purposes. We will participate in meetings or phone calls between you and your tax professional with your approval. ● Income Tax Preparation: Great Hill Advisory, also dba Bayside Tax & Wealth, includes individual income tax preparation as an included service for our full service wealth management clients. The included tax preparation is limited to the clients personal tax preparation and does not include business returns, including Sch C, E or F, or tax preparation for other family members. Business tax returns and returns for other family members will be billed separately. Investment Management Services We are in the business of managing individually tailored investment portfolios. Our firm provides continuous advice to a client regarding the investment of client funds based on the individual needs of the client. Through personal discussions in which goals and objectives based on a client's particular circumstances are established, we develop a client's personal investment policy or an investment plan with an asset allocation target and create and manage a portfolio based on that policy and allocation target. During our data-gathering process, we determine the client’s individual objectives, time 6  horizons, risk tolerance, and liquidity needs. We may also review and discuss a client’s prior investment history, as well as family composition and background. Account supervision is guided by the stated objectives of the client (i.e., maximum capital appreciation, growth, income, or growth and income), as well as tax considerations. Clients may impose reasonable restrictions on investing in certain securities, types of securities, or industry sectors. Fees pertaining to this service are outlined in Item 5 of this brochure. Investment Management Services - Use of Third Party Managers We offer investment management services by referring clients, where appropriate, to third-party money managers (“Outside Managers”) for portfolio management services. We assist clients in selecting an appropriate allocation model, completing the Outside Manager’s investor profile questionnaire, interacting with the Outside Manager and reviewing the Outside Manager. Our review process and analysis of outside managers is further discussed in Item 8 of this Form ADV Part 2A. Client may impose reasonable restrictions on their account. Additionally, we will meet with the client on a periodic basis to discuss changes in their personal or financial situation, suitability, and any new or revised restrictions to be applied to the account. Fees pertaining to this service are outlined in Item 5 of this brochure. One of the third-party managers that Great Hill Advisory may recommend is Alpha Partners Management, LLC (“Alpha”). The principal of Alpha and certain members of their family are personal advisory clients of Great Hill Advisory and receive advisory services generally under the same fee schedule and service model available to similarly situated clients. In addition, Great Hill Advisory may receive compensation from Alpha or Alpha-related entities for tax preparation, tax compliance, tax planning, bookkeeping, or other non-investment advisory services. Such compensation is separate from advisory fees paid to Great Hill Advisory and creates an incentive for Great Hill Advisory to continue or expand the business relationship with Alpha. Separately, Corey Peterson, principal owner of Great Hill Advisory, through HARP Investments LLC, may invest personally in certain private investment opportunities, including investment vehicles managed by Alpha, that may also be recommended to advisory clients. These investments are made for personal investment purposes and are not funded with client assets. Great Hill Advisory does not receive compensation based on client participation in those investments. These relationships create potential conflicts of interest because Great Hill Advisory and related persons may benefit may benefit from maintaining relationships with investment managers or participating in investment opportunities that are also available to clients. Great Hill Advisory addresses these conflicts by making recommendations based on client suitability and objectives, disclosing material conflicts prior to investment where applicable, and maintaining policies designed to ensure clients are treated fairly and consistently. Client Tailored Services and Client Imposed Restrictions 7  We offer the same suite of services to all of our clients. However, specific client financial plans and their implementation are dependent upon the client Risk Tolerance Questionnaire and Investment Policy Statement which outlines each client’s current financial situation (income, tax levels, and risk tolerance levels) and is used to construct a client specific plan to aid in the selection of a portfolio that matches restrictions, needs, and targets. Wrap Fee Programs We do not participate in wrap fee programs. Item 5: Fees and Compensation Please note, unless a client has received the firm’s disclosure brochure at least 48 hours prior to signing the investment advisory contract, the investment advisory contract may be terminated by the client within five (5) business days of signing the contract without incurring any advisory fees. How we are paid depends on the level of advisory service we are performing. Please review the fee and compensation information below. We define liquid assets as they are represented on the net worth statements we maintain and include retirement and non-retirement assets. Comprehensive Financial Planning - Retainer Fee Great Hill Advisory, Ltd., also dba Bayside Tax and Wealth, has a quarterly retainer fee starting at an annualized 0.7% of investable assets, with a minimum annual fee of $3,000 per year. The fee is computed and billed in advance each quarter based on the total liquid assets as reported on the clients net worth statement. After the first full year of service, if a client wishes to end our relationship during the year we will refund the unearned prorated fee for the remainder of the quarter. If a client wishes to end the relationship before the first full year is complete we have the right to bill the remaining amount of the first full year fee. The initial fee covers a prorated current quarter and the following quarter. 8  Third Party Investment Advisors Great Hill Advisory may coordinate with third-party investment advisers, private fund managers, or outside investment managers to implement portions of a client’s investment strategy where we determine those services may benefit the client. In certain situations, Great Hill Advisory also provides separate non-investment advisory services, including tax preparation, tax compliance, tax planning, bookkeeping, and related consulting services to investment managers, private funds, or affiliated operating entities. Compensation received for those non-investment advisory services is separate from advisory fees paid by advisory clients. This arrangement creates a conflict of interest because Great Hill Advisory has a financial incentive to maintain business relationships with entities whose investment products or services may also be recommended to advisory clients. Great Hill Advisory does not receive commissions, referral fees, placement fees, revenue sharing payments, or compensation based upon client investment decisions unless otherwise specifically disclosed. Recommendations involving outside investment managers are made based on Great Hill Advisory’s assessment of client suitability, objectives, and overall financial circumstances. Clients are under no obligation to utilize any investment manager or investment opportunity recommended by Great Hill Advisory. Other Types of Fees and Expenses When implementing an investment recommendation, the client may incur additional fees such as brokerage commissions, transaction fees, and other related costs and expenses. Clients may incur certain charges imposed by broker-dealers, and other third parties such as custodial fees, deferred sales charges, odd-lot differentials, transfer taxes, wire transfer and electronic fund fees, and other fees and taxes on brokerage accounts and securities transactions. Mutual fund and exchange traded funds also charge internal management fees, which are disclosed in a fund’s prospectus. Such charges, fees and commissions are exclusive of and in addition to our fee, and we shall not receive any portion of these commissions, fees, and costs. We do not accept compensation for the sale of securities or other investment products including asset-based sales charges or service fees from the sale of mutual funds. 9  Item 6: Performance-Based Fees and Side-By-Side Management We do not offer performance-based fees. Item 7: Types of Clients We provide financial planning and portfolio management services to individuals, high net-worth individuals (defined as having a liquid net-worth of $2MM) and charitable organizations. We do not have a minimum account size requirement. Item 8: Methods of Analysis, Investment Strategies and Risk of Loss Passive Investment Management We primarily practice passive investment management. Passive investing involves building portfolios that are comprised of various distinct asset classes. The asset classes are weighted in a manner to achieve a desired relationship between correlation, risk and return. Funds that passively capture the returns of the desired asset classes are placed in the portfolio. The funds that are used to build passive portfolios are typically index mutual funds or exchange traded funds. Passive investment management is characterized by low portfolio expenses (i.e. the funds inside the portfolio have low internal costs), minimal trading costs (due to infrequent trading activity), and relative tax efficiency (because the funds inside the portfolio are tax efficient and turnover inside the portfolio is minimal). In contrast, active management involves a single manager or managers who employ some method, strategy or technique to construct a portfolio that is intended to generate returns that are greater than 10  the broader market or a designated benchmark. Academic research indicates most active managers underperform the market. Overall portfolios and underlying managers, including third party managers, are reviewed on an annual basis, if not more regularly, to ensure their portfolio management is still inline with the original investment thesis they were hired for. Material Risks Involved All investing strategies we offer involve risk and may result in a loss of your original investment which you should be prepared to bear. Many of these risks apply equally to stocks, bonds, commodities and any other investment or security. Material risks associated with our investment strategies are listed below. Market Risk: Market risk involves the possibility that an investment’s current market value will fall because of a general market decline, reducing the value of the investment regardless of the operational success of the issuer’s operations or its financial condition. Interest Rate Risk: Bond (fixed income) prices generally fall when interest rates rise, and the value may fall below par value or the principal investment. The opposite is also generally true: bond prices generally rise when interest rates fall. In general, fixed income securities with longer maturities are more sensitive to these price changes. Most other investments are also sensitive to the level and direction of interest rates. Inflation: Inflation may erode the buying-power of your investment portfolio, even if the dollar value of your investments remains the same. Risks Associated with Securities Apart from the general risks outlined above which apply to all types of investments, specific securities may have other risks. Exchange Traded Funds prices may vary significantly from the Net Asset Value due to market conditions. Certain Exchange Traded Funds may not track underlying benchmarks as expected. Investment Companies Risk. When a client invests in open end mutual funds or ETFs, the client indirectly bears its proportionate share of any fees and expenses payable directly by those funds. Therefore, the client will incur higher expenses, many of which may be duplicative. In addition, the client’s overall portfolio may be affected by losses of an underlying fund and the level of risk arising from the investment practices of an underlying fund (such as the use of derivatives). ETFs are also subject to the following risks: (i) an ETF’s shares may trade at a market price that is above or below their net asset value; (ii) the ETF may employ an investment strategy that utilizes high leverage ratios; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit 11  breakers” (which are tied to large decreases in stock prices) halts stock trading generally. The Adviser has no control over the risks taken by the underlying funds in which clients invest. Item 9: Disciplinary Information Registered investment advisers are required to disclose all material facts regarding any legal or disciplinary events that would be material to your evaluation of GH or the integrity of our management. We have no information applicable to this Item. Item 10: Other Financial Industry Activities and Affiliations Great Hill Advisory is not affiliated with any registered investment adviser, broker-dealer, commodity pool operator, insurance company, or other registered financial institution. Certain supervised persons engage in outside business activities as described below. However, Corey Henry Peterson, the principal owner of Great Hill Advisory, is affiliated with the following entities: HARP Investments LLC HARP Investments LLC is a private family investment vehicle owned and controlled by Corey Henry Peterson. HARP is not offered to advisory clients and client assets are not invested through HARP. From time to time, HARP may invest in certain private investment opportunities, including private funds or investment vehicles that may also be recommended to advisory clients where Great Hill Advisory determines such investments are appropriate based on the client’s objectives and circumstances. As a result, Mr. Peterson’s personal investment activities may overlap with investment opportunities recommended to clients. This overlap creates a conflict of interest because Mr. Peterson may have a financial interest in investment opportunities that are also available to clients. Great Hill Advisory addresses this conflict by making recommendations based on client suitability and investment objectives, maintaining policies designed to promote fair treatment among clients, and disclosing material conflicts where appropriate. Great Hill Advisory does not allocate client assets to HARP and does not engage in cross-transactions with HARP. 12  Alpha Partners Management, LLC Great Hill Advisory may recommend investment opportunities managed by Alpha Partners Management, LLC (“Alpha”) for certain clients. The principal of Alpha and certain family members are personal advisory clients of Great Hill Advisory and receive advisory services under generally similar arrangements available to similarly situated clients. Separately, Great Hill Advisory may provide tax preparation, tax compliance, tax planning, bookkeeping, or related services directly to Alpha or Alpha-related entities and may receive compensation for those services. Such compensation is separate from investment advisory compensation and creates a conflict of interest because Great Hill Advisory has a financial incentive to maintain or expand its business relationship with Alpha. Great Hill Advisory does not receive compensation from Alpha for recommending advisory clients to Alpha investment opportunities and does not receive referral fees based upon client investments. Investment recommendations involving Alpha are based upon Great Hill Advisory’s assessment of client suitability, investment objectives, and overall financial circumstances. Clients are under no obligation to invest in opportunities associated with Alpha and may select alternative investment opportunities. Grace Marena I LLC Grace Marena I LLC is a real estate holding company owned and controlled by Mr. Peterson. Grace Marena I LLC leases office space to Great Hill Advisory. The lease arrangement is conducted at fair market value and on arm’s-length terms. Ridge End Partners (Outside Business Activity of a Supervised Person) Karen Ghaffari, a supervised person of Great Hill Advisory, serves as Co-Founder and Chief Financial Officer of Ridge End Partners, an entity owned by her spouse that manages personal family investments. Ridge End Partners does not provide advisory services to third parties and is not registered as an investment adviser. 13  Ms. Ghaffari’s role at Ridge End Partners is limited to administrative and bookkeeping functions. She does not participate in investment decision-making for that entity and does not provide advisory services to Ridge End through Great Hill Advisory. Great Hill Advisory does not allocate client assets to Ridge End Partners, does not engage in cross-transactions with Ridge End Partners, and does not receive compensation from Ridge End Partners. Item 11: Code of Ethics, Participation or Interest in Client Transactions and Personal Trading As a fiduciary, our firm and its associates have a duty of utmost good faith to act solely in the best interests of each client. Our clients entrust us with their funds and personal information, which in turn places a high standard on our conduct and integrity. Our fiduciary duty is a core aspect of our Code of Ethics and represents the expected basis of all of our dealings. The firm also adheres to the Code of Ethics and Professional Responsibility adopted by the CFP® Board of Standards Inc., and accepts the obligation not only to comply with the mandates and requirements of all applicable laws and regulations but also to take responsibility to act in an ethical and professionally responsible manner in all professional services and activities. This code does not attempt to identify all possible conflicts of interest, and literal compliance with each of its specific provisions will not shield associated persons from liability for personal trading or other conduct that violates a fiduciary duty to advisory clients. A summary of the Code of Ethics' Principles is outlined below. ● Integrity - Associated persons shall offer and provide professional services with integrity. ● Objectivity - Associated persons shall be objective in providing professional services to clients. ● Competence - Associated persons shall provide services to clients competently and maintain the necessary knowledge and skill to continue to do so in those areas in which they are engaged. ● Fairness - Associated persons shall perform professional services in a manner that is fair and reasonable to clients, principals, partners, and employers, and shall disclose conflict(s) of interest in providing such services. ● Confidentiality - Associated persons shall not disclose confidential client information without the specific consent of the client unless in response to proper legal process, or as required by law. 14  ● Professionalism - Associated persons’ conduct in all matter shall reflect credit of the profession. ● Diligence - Associated persons shall act diligently in providing professional services. ● We will, upon request, promptly provide a complete code of ethics. ● A recommendation made to one client may be different in nature or in timing from a recommendation made to a different client. Clients often have different objectives and risk tolerances. At no time, however, will our firm or any related party receive preferential treatment over our clients. Item 12: Brokerage Practices Factors Used to Select Custodians and/or Broker-Dealers Great Hill Advisory does not have any affiliation with Broker-Dealers. Specific custodian recommendations are made to client based on their need for such services. We recommend custodians based on the reputation and services provided by the firm. 1. Research and Other Soft-Dollar Benefits We currently do not receive soft dollar benefits. 2. Brokerage for Client Referrals We receive no referrals from a broker-dealer or third party in exchange for using that broker-dealer or third party. 3. Clients Directing Which Broker/Dealer/Custodian to Use We do recommend a specific custodian for clients to use, however, clients may custody their assets at a custodian of their choice. Clients may also direct us to use a specific broker-dealer to execute transactions. By allowing clients to choose a specific custodian, we may be unable to achieve the most favorable execution of client transactions and this may cost clients money over using a lower-cost custodian. Aggregating (Block) Trading for Multiple Client Accounts Great Hill Advisory occasionally makes trades in Blocks and allocates the shares to specific client accounts. We do this to provide the same execution price to all clients. This is particularly helpful when purchasing or selling publicly traded investments that do not have significant trading volume. Item 13: Review of Accounts Client accounts with the Investment Management Service will be reviewed regularly on a quarterly 15  basis by Corey Henry Peterson. During the regular review the account's performance is compared against like-managed accounts to identify any unacceptable performance deviation. Additionally, reasonable client imposed restrictions will be reviewed to confirm that they are being enforced. Events that may trigger a special review would be unusual performance, addition or deletions of client imposed restrictions, excessive draw-down, volatility in performance, or buy and sell decisions from the firm or per client's needs. Clients will receive trade confirmations from the custodian(s) for each transaction in their accounts as well as monthly or quarterly statements and annual tax reporting statements from their custodian showing all activity in the accounts, such as receipt of dividends and interest. GH will provide written reports to Investment Management clients on a quarterly basis. We urge clients to compare these reports against the account statements they receive from their custodian. Item 14: Client Referrals and Other Compensation Great Hill Advisory does not receive compensation from third parties in exchange for recommending securities, investment products, or investment advisory services to clients unless specifically disclosed in this brochure or other client materials. From time to time, Great Hill Advisory may receive compensation for non-investment advisory services, including tax preparation, tax compliance, tax planning, bookkeeping, or related consulting services provided to third parties, including investment managers, private funds, or affiliated operating entities. Where Great Hill Advisory recommends investment opportunities sponsored, managed, or associated with an entity that separately compensates Great Hill Advisory for non-investment advisory services, a conflict of interest may exist because Great Hill Advisory has a financial incentive to maintain that relationship. Great Hill Advisory seeks to address these conflicts by evaluating investment opportunities based on client objectives and suitability, maintaining fiduciary obligations to clients, and providing disclosure of material conflicts where appropriate. Great Hill Advisory does not pay cash compensation to non-employees for client referrals unless separately disclosed in accordance with applicable regulations. 16  Item 15: Custody Great Hill Advisory does not maintain physical custody of client cash or securities. In certain limited circumstances, Great Hill Advisory may be deemed to have custody under applicable securities regulations, including where clients authorize direct deduction of advisory fees from accounts maintained at qualified custodians. Client assets are maintained with qualified custodians that deliver account statements directly to clients no less frequently than quarterly. Clients should carefully review custodial statements and compare them to any reports provided by Great Hill Advisory. Great Hill Advisory periodically reviews its services and account arrangements to determine whether additional custody-related requirements apply under applicable regulations and will comply with applicable regulatory requirements. Item 16: Investment Discretion For those client accounts where we provide investment management services, we maintain discretion over client accounts with respect to securities to be bought and sold and the amount of securities to be bought and sold. Investment discretion is explained to clients in detail when an advisory relationship has commenced. At the start of the advisory relationship, the client will execute a Limited Power of Attorney which will grant our firm discretion over the account. Additionally, the discretionary relationship will be outlined in the advisory contract and signed by the client. Item 17: Voting Client Securities We do not vote Client proxies. Clients that wish to vote proxies or corporate actions can elect to do so when opening their accounts or make changes anytime after. Clients that elect to vote maintain exclusive responsibility for: (1) voting proxies, and (2) acting on corporate actions pertaining to the Client’s investment assets. 17  Item 18: Financial Information Registered investment advisers are required to provide you with certain financial information or disclosure about our financial condition. We do not require the prepayment of more than $1,200, six or months in advance. Additionally, we have no financial commitment that impairs our ability to meet contractual and fiduciary commitments to clients, and we have not been the subject of a bankruptcy proceeding. 18  Great Hill Advisory Form ADV Part 2B – Brochure Supplement Corey Henry Peterson Founder, President & Chief Compliance Officer Great Hill Advisory, Ltd. 174 Main Street Port Washington, NY 11050 Phone: 516-500-1248 Date: January 1, 2026 This brochure supplement provides information about Corey Henry Peterson that supplements the Great Hill Advisory, Ltd.
