Dr. Gregory specializes in pelvic organ prolapse, fecal incontinence and childbirth-related changes to the pelvis. His research interests include pelvic floor imaging (ultrasound and MRI), pelvic neurophysiology, and pelvic floor neuromuscular injury associated with pregnancy and childbirth. Dr. Gregory had a congenital heart problem that was not diagnosed until he was 11 years old. His successful heart surgery dramatically influenced his desire to become a doctor so that he could help people in a similar way. He advises patients to explore the variety of options available for their conditions with their healthcare provider.

Before moving to Portland, Dr. Gregory lived in Tampa, Florida, the San Francisco Bay Area and Los Angeles. In his spare time, he enjoys playing golf, and spending time with his wife and daughter.
