About Us

Dufek & Company, LLC is a certified public accounting firm conducting 401k and profit-sharing plan audits.  Our motto "respect your own time" governs everything we do.  Our audit process is designed to respect your time, and, whenever possible, we work directly with your service providers and try to answer our own questions before they are posed to you.

We are unlike most CPA firms in that the owners complete your entire audit.  By working directly with the owners, you can be confident things will be done correctly the first time. The continuity of working with people you know and trust also means you will not have to battle a continual learning curve. 

Another major distinction is that we are not a full-service accounting firm as we only perform 401(k) and profit-sharing plan audits.  Our high level of audit quality is demonstrated by our membership in the American Institute of Certified Public Accountants' (AICPA) Employee Benefit Plan Audit Quality Center.
