Who We Are
Celebrating our 45th year in 2019, Crain’s Chicago Business and the Daily Herald Business Ledger consistently rank Dugan & Lopatka, CPAs as one of the top accounting firms in the Chicagoland area.
Our clients are diverse both as to size and the nature of their organizations. They include manufacturers, real estate developers, construction contractors, distribution companies, service and professional firms, healthcare corporations, and not-for-profit organizations and associations.
Serving all of the Chicago area, Dugan & Lopatka is conveniently located along the Ronald Reagan Memorial Tollway (I-88) at Winfield Road in Warrenville, Illinois.
Because of our size, our clients are assured of working closely with an experienced professional. We assign a team of professionals to serve you, including at least two firm principals. Our goal is to 1) have someone always available when you call and 2) to pull in the team of people with the specific skills.
