“Mark knows more about performance auditing than anyone in this country, whether you're talking history and theory or practical application. Mark is able to combine his passion with an intimate knowledge of both the theoretical and practical sides of performance auditing, and to weave in his own brand of thoughtful and thought-provoking insights into the auditing profession. That's what keeps us coming back to Mark again and again.”

- Jerry Heer, County Auditor, Milwaukee County
