About

Grove Street Fiduciary serves individuals (including high‑net‑worth clients), trusts, estates, qualified retirement plans, charitable organizations, and other business entities, offering wealth and trust advisory services that combine financial planning with discretionary investment management, along with consulting and limited pension consulting. The firm reports about $413 million in assets under management across roughly 292 client relationships and operates with two advising professionals.

The firm’s investment approach emphasizes globally diversified asset allocation implemented primarily through exchange‑traded funds, index funds, and no‑load indexed mutual funds, using Modern Portfolio Theory alongside technical, fundamental, and cyclical analysis. Advisors prepare a personalized investment policy for each client, generally manage accounts on a discretionary basis within client guidelines, and disclose that tax efficiency is not a primary consideration—clients are advised to consult tax professionals.

Distinctive features include offering educational seminars and workshops as part of its consulting services and providing standalone hourly consulting engagements with a stated initial consultation fee in addition to its asset‑based wealth management agreements. The firm also maintains a stated $5,000,000 investable asset guideline for wealth and trust advisory services (subject to discretionary waiver), a relatively concentrated advisor-to‑AUM ratio, and uses institutional custodians (including Schwab) with tax‑lot optimization for account administration.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.

Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.

For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
