Eos Financial Planning

Eos Financial Planning

Eos Financial Planning was established in 2017 and maintains its primary office in Arlington, Massachusetts. The firm is structured as a fee-only registered investment advisor, a regulatory posture that legally binds it to a fiduciary standard—meaning it must place client interests ahead of its own revenue incentives. Its client base spans individual professionals, high-net-worth households, charitable entities, and corporate accounts, all served through a combination of comprehensive financial planning and discretionary portfolio management. The firm's investment approach centers on passive, factor-based portfolio construction rather than active security selection. Client assets are typically allocated across broad-market equity and fixed-income exposures through low-cost ETFs and index funds, with explicit integration of tax-efficiency overlays for taxable accounts. Asset class coverage includes US equities, international developed and emerging-market equities, taxable and municipal fixed income, and real estate investment trusts. The firm does not originate direct private investments, venture deals, or proprietary alternative products. Geographic focus remains concentrated in the domestic US market, reflecting both the firm's local advisory footprint and the home bias inherent in its passive implementation. Eos operates as a boutique practice without disclosed assets under management or professional headcount. The absence of publicly reported AUM is common among smaller independent RIAs that fall below SEC reporting thresholds. The firm's website describes service capabilities in investment advisory, retirement planning, and educational seminars, but no named principals, portfolio holdings, or recent operational milestones appear in the public domain as of mid-2026. Eos does not publicize club memberships, adjacent philanthropic vehicles, or co-investment structures. As a locally anchored RIA, Eos's structural differentiator lies in regulatory simplicity. The firm is not part of a roll-up platform, does not operate under a broker-dealer umbrella, and carries no disclosed conflicts tied to proprietary product distribution. This architecture—a standalone fiduciary shop without institutional scale—places it in a category where client trust is the primary asset and growth is constrained by partner bandwidth rather than acquisition capital.
