What is your favorite thing about being a lawyer?
I went to law school because I wanted to help real people with their problems. A family business may be someone’s most valuable asset and the sole source of their livelihood, and in my practice I have the opportunity to help solve the stresses a business owner faces, to help those businesses compete and remain an employer in their community, and help ensure that those business owners can sleep at night.
What is the best vacation you’ve ever been on? My honeymoon to Charleston, South Carolina, and Savannah, Georgia.
What is your favorite restaurant? Aurelio’s Pizza in Homewood, Illinois
