About me

Dr. Sean Orenstein is an Associate Professor of Surgery, joining OHSU in 2014. While he grew up in Colorado and completed his undergraduate work at the University of Colorado, he spent most of his medical and surgical training on the East coast. After receiving a Master of Medical Science from MCP Hahnemann University in Philadelphia, PA, he received his medical degree from Albany Medical College. During his general surgery residency at the University of Connecticut School of Medicine, he undertook a two-year research fellowship, with focuses on the evaluation of hernia mesh materials and hernia repair outcomes.

After finishing his surgical residency, Dr. Orenstein completed a fellowship at University Hospitals Case Medical Center in Cleveland, OH. Fellowship allowed him to further explore his passion for hernia repair, with specialized training in abdominal wall reconstruction for complex and recurrent abdominal hernias. During his fellowship he had the opportunity to focus 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’s 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.
