Geller & Lehmann
The Family Financial Group operates through two integrated affiliates: Geller & Lehmann LLC and Lehmann & Company LLC. The group was formed when the founders combined their respective decades of accounting and financial planning experience. Geller, a CFP professional since 2004, anchors the family office consulting and philanthropic advisory work. Lehmann, who earned his CPA designation in 1993 and CFP certification in 2003, leads the tax and accounting practice. The firm does not publicly disclose the source of wealth for the families it serves. The firm structures client capital across private equity, real estate, and fund-of-funds vehicles, with a geographic focus on North America. Its real estate exposure includes a directly managed portfolio of mixed-use shopping center assets located in Maryland and Massachusetts. Public records do not name specific private equity fund commitments or co-investment partners, and the firm did not respond to sourcing requests. The tax practice — led by CPAs Atara Miller and Miriam Lipsky — supports the investment strategy by providing compliance, estate planning, and representation before the IRS, ensuring alignment between asset structuring and intergenerational transfer goals. The firm lists seven professionals, including four CPA-designated team members and two CFP holders. A second office in Newton Centre, Massachusetts extends its physical footprint beyond the Pikesville headquarters. The practice has not disclosed recent operational milestones, and no public filings mark a dated event in the past 24 months. The absence of press releases and the low AUM band of $100M–$250M reflect a client base served through word-of-mouth and professional-network referrals rather than institutional marketing. The structural differentiator is the integration of a licensed CPA firm with an SEC-exempt multi-family office. This architecture allows Geller and Lehmann to provide tax preparation, estate planning, and investment management within a single entity, making them an outsourced family-office solution for clients who do not require a standalone single-family office. The model positions the firm as a continuity tool for families that value accountant-grade fiduciary oversight alongside asset-allocation advice — a posture more common among Midwest and Mid-Atlantic multi-generational practices than among coastal wealth managers.

Frequently asked questions
Who runs investment decisions at Geller & Lehmann?
Investment and planning decisions sit with founding members Sandra V. Geller and David C. Lehmann. Geller, a CFP professional, manages the family office consulting and philanthropic advisory arm. Lehmann, a CPA/PFS and CFP professional, oversees the tax and accounting practice. They are supported by tax specialists Atara Miller and Miriam Lipsky, both CPAs, who handle compliance and income tax preparation. The firm has not publicly designated a separate CIO or investment committee.
Is Geller & Lehmann structured as a single family office or does it operate more like an accounting firm?
The firm is structured as a multi-family office embedded within an accounting practice. It operates under The Family Financial Group umbrella, which includes Geller & Lehmann LLC and Lehmann & Company LLC. This dual structure means clients receive integrated CPA-led tax and estate planning alongside investment advisory services, rather than a siloed family-office model. The firm markets itself as a 'boutique multi-family office' with a heavy emphasis on tax compliance and financial reporting.
Does Geller & Lehmann participate in fund commitments or only direct deals?
The firm deploys client capital through fund-of-funds vehicles and direct investments in private equity and real estate. Its real estate activity includes a directly owned and managed mixed-use shopping center portfolio in Maryland and Massachusetts. Specific fund commitments are not publicly disclosed, and the firm did not provide a breakdown between direct and fund allocations.
How does Geller & Lehmann source new clients?
The firm does not maintain a public-facing institutional marketing presence. Its client base appears to be built through professional networks, including affiliations with the Financial Planning Association and the American Institute of Certified Public Accountants. The practice is concentrated in the Mid-Atlantic and New England regions, with offices in Pikesville, Maryland and Newton Centre, Massachusetts.
Does the firm maintain philanthropic structures, and how are they separated?
Sandra Geller's practice explicitly includes philanthropic and legacy consulting, and the firm prepares tax returns for foundations. However, the firm does not advertise a separate philanthropic entity or donor-advised fund program. Philanthropic advisory is integrated into the family-office service line rather than operated through a distinct legal vehicle.
What is Geller & Lehmann's known posture on co-investments alongside external GPs?
The firm's publicly available materials do not reference co-investment programs or club-deal arrangements with external general partners. Its investment activity is described as fund-of-funds, private equity, and real estate, with no mention of side-by-side co-investment vehicles. An allocator should expect a primarily intermediated investment approach rather than direct GP-level co-investment participation.
