Charles Leys, MD, MSCI, FACS


Charles Leys, MD, MSCI, FACS, is a UW Health Kids pediatric surgeon and a professor in the Department of Surgery at the University of Wisconsin School of Medicine and Public Health. Dr. Leys provides surgical care for babies and children of all ages, from premature babies through teenagers. He performs a wide range of surgical procedures, focusing on chest and abdominal conditions.

Dr. Leys regularly cares for kids with abnormalities present at birth, chest disorders, chest wall deformities and tumors. He also provides surgical care for digestive disorders such as inflammatory bowel disease and acid reflux. 

He has a special clinical interest in minimally invasive surgery. Dr. Leys is always looking for new innovative techniques that result in less pain, shorter hospital stays and quicker recovery for kids. Dr. Leys loves to solve problems and help people; pediatric surgery allows him to do both every day.

Outside of work, Dr. Leys enjoys being outdoors, cycling and spending time with his family.

I really see the entire family as my patient — it’s not just the child, but also the parents or caregivers who bring them in.
