    • About

      Dugan & Lopatka, CPA's, PC, is a leading, highly respected, regional business advisory firm located in Warrenville, Illinois. The Business Ledger consistently ranks our firm as one of the largest accounting and consulting firms in Chicago's suburbs. Our client base has continued to grow since our firm's beginning in 1974, as has our reputation for timely, cost-effective, quality service.

      Our goal is to be the preeminent accounting and consulting firm serving privately held and family owned small and mid-sized companies and nonprofit organizations in industries including construction, manufacturing, distribution, not-for-profits, professional services, trucking and transportation, real estate, and commercial services.

      While many CPA firms are preparation and compliance oriented, little attention is given to the planning opportunities available to their clients. Dugan & Lopatka's philosophy, however, is to successfully integrate these planning opportunities with our preparation, compliance, and audit work.
