Grove Street Fiduciary

Grove Street Fiduciary

Grove Street Fiduciary was established in 1991 and maintains its headquarters in Peterborough, New Hampshire. The firm is registered with the SEC as a Registered Investment Advisor, a structure that legally binds it to a fiduciary standard when advising clients. Peterborough, a small Monadnock-region town, is not a typical financial hub, suggesting the firm was built around local or regional relationships rather than a national institutional rollout. The firm's ADV filings describe its client base as individuals, high-net-worth individuals, pension and profit-sharing plans, trusts, estates, and charitable organizations, as well as corporations and other business entities. Grove Street provides portfolio management and financial planning, with clients able to impose restrictions on their accounts. The advisory model operates on a percentage of assets under management, with some clients paying fixed fees. The firm does not list participation in direct co-investments, fund-of-funds, or club deals, pointing to a more traditional RIA posture — constructing portfolios from publicly available securities and mutual funds for a regional clientele. Team size and total regulatory assets are not publicly disclosed in available filings. As a small-state RIA, the firm likely operates with a compact team serving a concentrated book of local families and small institutions. No additional offices are listed beyond the Peterborough location, and there is no record of affiliated philanthropic vehicles, real-asset arms, or operating businesses associated with the firm. Grove Street's regulatory record shows no disciplinary events, a mark of operational consistency over three decades. Grove Street's primary differentiator is structural: it is a fiduciary RIA in a market segment dominated by broker-dealers and insurance-affiliated advisors. The firm's longevity in a small New England town suggests it has succeeded through a conservative, relationship-driven model — the kind of practice where clients value continuity and a personal trustee relationship over platform scale or proprietary product.
