Anthony Duffy

Senior Counsel

In public accounting since 1980, Tony has been a Senior Counsel Member at Bonadio, providing business valuation, succession planning, and litigation support, including related consulting services. ValuQuest has worked with more than 1,500 companies and their management teams throughout the Northeast to solve various planning and reporting issues and business valuation measurements. Tony regularly authors numerous articles and frequently speaks at conferences and events.

Tony has served on many charity boards. From the Cancer Society, St. Jude's, and Siena College to the Children's Museum and American Heart, Tony has always tried to give back purposefully. As empty nesters, Tony and his wife, Donna, stay busy with family, friends, community, and golf, which are only sometimes in that order in both N.Y. and Florida.
