Hertzbach

What Hertzbach does

Hertzbach & Company, P.A. was a privately held professional services corporation organized as a CPA firm that provided accounting, audit, tax, and advisory services to mid-to-large organizations across three Mid-Atlantic markets: Baltimore, Northern Virginia, and Greater Washington, D.C. The firm operated as a regional practice with a people-centered culture and longstanding client relationships, generating revenue through fee-based professional services engagements on a quote-based, customized pricing model typical of accounting firms. Pricing was not publicly disclosed, consistent with standard professional services norms.

The firm was a member of the BDO Alliance for more than 17 years prior to November 16, 2020, maintaining an affiliated but independent relationship with the BDO global network. On that date, Hertzbach & Company, P.A. was acquired by BDO USA, with its partners and professionals continuing under the BDO brand. The acquisition extended BDO's footprint in the Greater Baltimore market and throughout the Atlantic region, while preserving client access to incumbent Hertzbach advisors and layering in BDO's broader service capabilities — including Audit & Assurance, Advisory, Tax, BDO Digital (encompassing artificial intelligence, cybersecurity, data analytics, and cloud & infrastructure consulting), Industry Specialty Consulting (government contracting and services, higher education, life sciences), and Sustainability/ESG services.

Following the 2020 transaction, Hertzbach no longer operates as an independent entity; the firm's revenue, headcount, and standalone financial profile are not disclosed in the source material, and the legal name Hertzbach & Company, P.A. now exists solely as a historical reference within BDO USA's Atlantic region practice. No proprietary technology, AI/ML capabilities, patents, or product launches are associated with the firm in the input data — its value resided in its professional talent, client relationships, and Mid-Atlantic market position.
