Anthony Duffy


In public accounting since 1980, Tony is the managing director of ValuQuest, LLC, a division of Bonadio providing business valuation, succession planning and litigation support, including the related consulting services. ValuQuest has worked with more than 1,500 companies and their management teams throughout the northeast to solve a wide variety of planning and reporting issues and business valuation measurement.

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 with purpose. Now as empty nesters, Tony and his wife, Donna, stay busy with family, friends, community and golf, not always in that order, in both N.Y. and Florida.
