Firm Profile


From a Kitchen Table to a Top 100 CPA Firm

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

Since then, TBG 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, we have grown to be the largest independent CPA and financial services firm in upstate New York, and nationally, we are a Top 100 CPA Firm. (Just to provide some perspective, there are currently over 46,000 CPA firms in the country.)

Our growth isn’t a function of happenstance—it’s a product of the hard work, professionalism and dedication of our partners and staff to going beyond client satisfaction to delivering extraordinary value. Whether we’re helping clients with compliance needs and issues, or finding ways to grow and protect their assets, TBG is known throughout upstate New York as the “& More” CPA and business advisory firm.

That’s why both Inside Public Accounting and Public Accounting Report named us a Top 100 CPA Firm in the U.S. But the accolades don’t stop there:

  • Named a Rochester Top 100 company each of the last ten years by the Rochester Business Journal
  • Named by The American Institute of Certified Public Accountants’ as a “Firm to Watch”
  • Identified by the Rochester Business Journal as the Top CPA firm in the Finger Lakes market
  • Identified by Buffalo Business First as a Top CPA firm in the Western New York market
  • Identified as the Largest independent CPA firm in New York State (outside of New York City) by the Syracuse Business Record
  • Named as a “Top Firm to Watch” by Public Accounting Review
  • Recognized as an “Innovative CPA Firm” by Practical Accountant
  • Attained membership in the prestigious AICPA's Major Firms Group
  • Honored by CPA Wealth Provider for innovation in Financial Services
  • “Best Places to Work” Award

We have offices in five locations (Rochester, Buffalo, Perry, Geneva, and Syracuse) with over 200 employees and revenues of approximately $22 million per year. We continue to add additional clients, while providing excellent service to our existing ones. It is this combination that has made us successful and is responsible for our growth.
