He has over 25 years of public accounting experience serving a wide variety of industries, with a particular emphasis on manufacturing, distribution and professional services firms.
Helping his clients save money and find successful tax and business strategies is a powerful motivator for Patrick, who relishes the relationships he builds as much as the variety of approaches he provides.

Patrick got his first accounting experience in high school, doing the books for his father’s business. He went on to study at the University of Missouri as an Evans Scholar (a scholarship for caddies run by the Western Golf Association) where he earned a Bachelor of Science in Accounting before pursuing his Masters in Taxation from DePaul University.
