Berman, Sosman & Rosenzweig CPAs

Berman, Sosman & Rosenzweig is a licensed public accounting firm, not a single-family or multi-family office in the strict sense. However, for business owners whose wealth is concentrated in a private operating company, a tax-centric CPA firm often serves as the functional family office before the family hires a dedicated CIO. The firm's partners act as long-term financial quarterbacks for tax planning, entity structuring, and estate freezes.

While the firm does not publish a client list, its Southfield location in the Detroit metropolitan area places it in close proximity to manufacturing and automotive-supply business owners. CPA firms structured around three named partners typically serve a concentrated roster of privately held companies, their shareholders, and multi-generational family trusts, often for decades at a time.

No. As a CPA firm, its core competency is tax compliance, tax strategy, and business consulting — not investment management. Registered investment advisory services would require separate registration with the SEC or the state of Michigan. The firm may coordinate with a family's outside wealth managers and estate attorneys to align portfolio decisions with tax planning, but it does not function as an RIA.

The firm's name implies that managing partners — presumably Berman, Sosman, and Rosenzweig — personally oversee key client engagements. In a mid-size CPA firm, this typically means a senior partner serves as the relationship anchor for each major family or business client, with junior accountants and managers handling preparation work. The structure rewards stability over growth, and clients rarely rotate off a partner's desk.

The firm operates from its office in Southfield, Michigan, a major professional-services hub northwest of Detroit. Its client base is likely concentrated in southeastern Michigan, though tax preparation and consulting can be conducted remotely for clients with multi-state interests. There is no indication of additional offices or a national footprint.
