About

Bio

I was raised in River Forest, Illinois. Attended Oak Park and River Forest High School 1966-1970, Purdue University 1970-1974, and Loyola Stritch School of Medicine 1974-1977. I did my Urology residency at Loyola Medical Center and Hines V.A. Medical Center including 6 months at Children's Memorial Hospital in Chicago, IL. 1977-1982. After completing my residency, entered private Urology practice in Joliet, IL in 1982 where I have been for the past 36 years and one of the original founders of Advanced Urology Associates (www.advuro.com). I am a Board-certified Urologist and an active staff member at PSJMC (Joliet), SCH (New Lenox), and Morris Hospital (Morris). I am married and have two wonderful sons. I enjoy golf, road biking, and am a certified Star Level 3 Spinning instructor.
