He joined the Oregon Clinic in 2016 after 20 years at the University of Southern California where he was Clinical Scholar and Professor of Cardiothoracic and Foregut Surgery. He earned his medical degree from Loyola Stritch School of Medicine, and subsequently completed both a general surgery residency and critical care fellowship at the University of Michigan.

He then went on to complete cardiothoracic surgery training, with special emphasis on general thoracic surgery, at Barnes Hospital, Washington University in St. Louis. To gain further expertise with complex foregut problems, and to refine his skills in minimally invasive laparoscopic and thoracoscopic procedures, he undertook a one-year esophageal surgery fellowship at USC, after which he joined the faculty there. He was full-time faculty at USC from 1996-2016

Dr DeMeester’s clinical practice focuses on innovative minimally invasive and endoscopic approaches to treat esophageal, gastric and mediastinal disorders as well as complex diaphragmatic and abdominal wall hernias. His research focuses on complex paraesophageal and abdominal wall hernias and techniques to reduce tension and hernia recurrence, the role of mesh in hernia repair, esophageal motility abnormalities, gastroesophageal reflux disease, Barrett’s esophagus, and esophageal cancer. His work has led to over 150 peer reviewed publications, numerous book chapters and invited lectures throughout the world.
