Secret to Success: “Get closer than ever to your customers. So close that you tell them what they need well before they realize it themselves.” –Steve Jobs



Brian has over 25 years of experience in public accounting and has worked closely with clients in a wide range of industries. He specializes in audits and tax planning and preparation for small business entities, financial institutions, and governmental bodies.


Brian grew up in St. Libory, IL and still lives in town today. He is an avid hunter and, when tax season subsides, enjoys spending time outdoors hunting and attending as many St. Louis Cardinals games as possible.
