Practicing in the Fox Valley for more than 20 years, Dr. Peter Janu is a general and laparoendoscopic surgeon who specializes in the latest heartburn, reflux and foregut procedures. He has become the region’s most comprehensive expert in the surgical treatment of reflux and developed a worldwide reputation for performing minimally invasive procedures like transoral incisionless fundoplication as well as magnetic sphincter augmentation. “I wanted to become a doctor since I was 12 and I really appreciate being able to help patients fix their health issues so they can enjoy a better quality of life,” he says. “With so many people suffering from heartburn and reflux problems, I found that my combination of training is uniquely suited for this specialty.”

Dr. Janu earned his bachelor’s degree from the University of Wisconsin-Madison, received his medical degree from the University of Wisconsin Medical School and completed surgical residency training at the University of Tennessee-Memphis. He is a Fellow of the American College of Surgeons, a founding member of the American Foregut Society and he also belongs to the Wisconsin Surgical Society.
