Dugan & Lopatka

Nonprofit Accountants and Auditors Serving Northern Illinois

Dugan & Lopatka

Dugan & Lopatka is not the only accounting and consulting firm that serves nonprofits. But there is a difference between a firm that specializes in serving the industry and a firm that serves nonprofits as a means of keeping its corporate accounting staff busy during the off-season. Our clients can readily see that difference in our innovative ideas, in the rewards our experience provides and through the quality of our work.


  • Audit Services

    You seek a firm that understands the nature of your organization – saving you time and effort during the audit and tax process and answering accounting questions throughout the year. Dugan & Lopatka has been meeting the needs of nonprofit organizations since 1974. We have a large staff dedicated to our nonprofit clients.

    Our clients can readily see the difference between a specialist and a general accounting and auditing firm in our innovative ideas, the rewards we bring to them from having a great deal of experience working with nonprofits and through the quality and timeliness of our work.

    We understand that most nonprofits have accounting and tax questions throughout the year, but limited funds to pay outside advisors for answers. Our long-standing policy is not to charge clients for routine phone calls. We want you to call us.
