Tom Bonadio, our Managing Partner, laid the foundation for The Bonadio Group (Bonadio) around his kitchen table in 1978 with one partner and his mother as the accounting firm’s administrative support.

Since then, Bonadio has grown and diversified from a CPA firm primarily offering tax and auditing services to a multi-dimensional accounting, tax, business advisory, and financial planning organization. Regionally, our accounting firm, Bonadio & Co., LLP, has grown to be the largest independent CPA and financial services firm in upstate New York, and nationally, it is a Top 100 CPA Firm.

Whether we’re helping clients with compliance needs and issues, or finding ways to grow and protect their assets, Bonadio is known throughout upstate New York for its “& More” accounting, business advisory, and financial services capabilities expertise.
