BDO USA, P.C. is the United States member firm of BDO International, a global professional services network founded in 1963 by five independent firms from the United States, United Kingdom, Germany, Netherlands, and Canada. Originally known as the Binder Seidman International Group, the network has expanded to span 169 countries with more than 860 offices worldwide. BDO USA ranks as the eighth-largest accounting and professional services firm in the United States, operating within a network that serves middle-market businesses and enterprises requiring specialized professional services.
The firm delivers four core service lines: assurance (audit and related services), tax advisory, financial advisory including merger and transaction guidance, and consulting services. Each service line is positioned to address the technical and regulatory requirements of clients across multiple industry verticals, with particular emphasis on navigating complex tax regulations and providing audit insights. BDO's approach centers on tailoring services to clients' specific industry contexts and operational requirements rather than offering standardized solutions.
BDO USA operates under CEO Wayne Berson and maintains a stated people-first philosophy that emphasizes supporting professionals while delivering client service. The firm's technical domains span accounting, assurance, audit, tax, financial advisory, and consulting work - disciplines that increasingly intersect with cybersecurity considerations as regulatory frameworks evolve and financial systems face persistent threat models. For professionals evaluating BDO USA, the firm's scale and industry positioning place it within the established tier of professional services organizations handling sensitive financial data and advisory work that requires understanding both technical controls and business risk.
