Our Team

Bariatric Physicians
Presence Saint Joseph Medical Center provides innovative, comprehensive and compassionate care for patients undergoing surgical options for weight loss.

The surgical team is lead by Dr. Peter Mihalakakos, Medical Director; Diane Hill, Bariatrics Coordinator, Anne Lietz, Bariatric Dietitian and Dr. Joanne Hattendorf, Psychologist.

Peter Mihalakakos, M.D., F.A.C.S., was nominated as a Physician of the Year Finalist for 2008.  "I’ve always been particularly interested in surgery, especially when it makes an improvement in someone’s life. With gastric bypass surgery, patients lose a significant amount of weight and feel so much better, both physically and mentally. They have a chance to do things they could never do before. In a way, I feel as if I’ve given them back their life," said Mihalakakos. Dr. Mihalakakos completed his residency at Loyola University Medical Center in General Surgery.

Brian J. Winkleman, MD, a specialist in Minimally Invasive and Bariatric Surgeon, has added to the advancement of procedures for surgical weight loss. He completed a General Surgery residency at The Ohio State University Medical Center. Dr. Winkleman's credentials also include fellowship training in Minimally Invasive and Bariatric Surgery.
