    • Assistant Professor of Surgery, Division of Gastrointestinal and General Surgery School of Medicine

Dr. Orenstein joined the OHSU Department of Surgery in 2014 as Assistant Professor of Surgery within the Division of Gastrointestinal and General Surgery.  His research interests include outcomes and improvements for minimally invasive and open hernia repair techniques, evaluation of hernia mesh prosthetics, and further exploration of the fusion between endoscopic and surgical techniques to improve patient outcomes and medical care.

Dr. Orenstein's residency and fellowship training allowed him to explore his passion for hernia repair, with specialized training in abdominal wall reconstruction for complex and recurrent abdominal hernias. During his fellowship he also focused on minimally invasive surgical techniques such as laparoscopic hernia repair, laparoscopic foregut surgery, and laparoscopic diaphragmatic pacemaker placement for Amyotrophic Lateral Sclerosis (ALS) or spinal cord injury. His fellowship was also an avenue to receive specialized training on advanced endoscopy, including per oral endoscopic myotomy (POEM) for achalasia, endoscopic retrograde cholangiopancreatography (ERCP), and endoscopic stenting.

Dr. Orenstein has held membership with the Association for Academic Surgery since 2008, and with the American College of Surgeons, Americas Hernia Society, and the Society of American Gastrointestinal and Endoscopic Surgeons since 2009.
