Mario Urso

Mario currently serves as Senior Counsel to the firm and co-founder of our Healthcare/Tax-Exempt team. He joined The Bonadio Group in 1990 after 12 years at a Big Eight accounting firm as a senior audit manager specializing in serving healthcare and tax-exempt organizations.

Mario is an avid cyclist. He enjoys long bike rides, especially early in the morning, when he can reflect on his day and enjoy the beauty of Upstate New York.

As evidenced by his board involvement, he is also dedicated to making a difference in the lives of city children, especially those who are disadvantaged and need a chance to succeed.
