    President & CEO
    312-957-4276

    Tom joined ACG in December 2019, after overseeing unprecedented growth at the North American Veterinary Community (NAVC). At NAVC, Tom was a force for operational change and expansion, taking the organization from $11 million to $26 million in less than six years.  

    In his first three years at ACG, Tom and his team propelled revenue forward from $8 to $16 million, and added several new products and services to the organization, including ACG’s first acquisition, GF Data.  

    A native of Queens, he takes a no-nonsense approach to life. He uses a straightforward management style to drive exceptional growth through new products and services, increased brand awareness and reach, and improved audience engagement via multiple revenue-producing media channels.  

    Tom, his wife Jennifer, and their two dogs split their time between New York and Bridgewater Connecticut, where he indulges in his love of music with a collection of more than 40 instruments and sound equipment in his home studio. Their son, Hudson, is a starting lacrosse player at Penn State.
