Kershner, Grosso & Co.
Kershner, Grosso & Co. (KGC) was founded in 1979 by Chris Grosso and his then-partner Thomas Kershner. Grosso built the firm from scratch, priding it on independent research and intuitive investments, and remains a principal today. The firm operates from Saratoga Springs, New York, without additional offices, serving individuals, trusts, corporations, and retirement plans. KGC's strategy rests on two parallel paths: exceeding client-service expectations and disciplined asset management. The firm holds discretionary authority over every account, allocating across high-growth equities and bonds while deliberately avoiding high turnover. It also serves as trustee or co-trustee for select clients, and has a network of external accountants and attorneys for estate planning and tax matters. KGC administers company retirement plans, including plan-sponsor meetings and administrative tasks. The firm's principals make all portfolio decisions based on their judgment and experience rather than a model-driven process. In 2025, KGC joined forces with Colley Asset Management, an established Saratoga Springs firm, bringing John Colley onto the principal team. The move consolidated two local books under a shared client-service philosophy. The firm lists six principals — Christopher Grosso, Timothy Fontaine, Gabrielle Hoyt, Vicki Bush, John Colley, and Tanya Gross — who collectively run the investment committee and client relationships. KGC does not operate any adjacent philanthropic foundations, club vehicles, or real-asset arms; it functions as a single-office, principals-led wealth manager. KGC's structural differentiator is its discretionary-only, high-conviction posture in a market dominated by model portfolios and home-office allocation teams. Every account is managed directly by the principals, with the flexibility to buy and sell without prior client consultation within agreed investment guidelines. The 2025 merger with Colley signals a succession-conscious consolidation rather than a growth-at-all-costs roll-up — two local firms merging to deepen their bench while preserving the independent research culture Chris Grosso established 46 years ago.

Frequently asked questions
Who runs investment decisions at Kershner, Grosso & Co.?
Investment decisions are made by the principals, led by co-founder Chris Grosso. The current principal group includes Christopher Grosso, Timothy Fontaine, Gabrielle Hoyt, Vicki Bush, John Colley, and Tanya Gross. KGC holds discretionary authority over every managed account, meaning the principals can buy and sell securities without prior client approval, within each client's agreed guidelines.
Is KGC a single-family office or a wealth manager?
KGC is a wealth manager and registered investment advisor, not a single-family office. It serves a diverse client base that includes individuals, high-net-worth individuals, trusts, corporations, and other business entities. The firm also provides trustee and co-trustee services for select clients, but does not manage capital for a single family.
What is KGC's investment approach?
KGC prioritizes high-growth equities and diversifies with bonds while deliberately avoiding high turnover. The firm describes its approach as disciplined asset management driven by the principals' independent research and judgment. Portfolios are tailored on a client-by-client basis with a preference for concentration in what the firm calls promising investment opportunities.
Does KGC commit to external funds or only manage direct portfolios?
KGC manages direct portfolios of equities and bonds on a discretionary basis. There is no indication in the firm's public materials that it participates in fund commitments, private capital allocations, or co-investments alongside external managers. The firm's model is entirely focused on direct, principals-led portfolio management.
How did the 2025 merger with Colley Asset Management change KGC?
The 2025 merger brought John Colley and his Saratoga Springs client base into KGC, adding a sixth principal to the team. The firms described the combination as reflecting a shared vision for client service and community engagement. Operationally, it deepened the firm's bench without changing its discretionary, high-conviction investment model.
Who has custody of client assets at KGC?
KGC does not hold custody of client assets directly. The firm's website points clients to Schwab Alliance for account login, indicating that Charles Schwab likely serves as the primary custodian. KGC manages the portfolios on a discretionary basis while the custodian holds the underlying securities.
Where does KGC source its investment ideas?
KGC relies on proprietary, independent research conducted by its principals rather than third-party model portfolios or external research aggregators. The firm states that all investment advice and portfolio decisions are informed by the judgment and experience of the principals, who conduct their own analysis of available information. There is no mention of a dedicated in-house analyst team beyond the named principals.
