Hi! I am currently a patient at OHSU in their bariatric program. I am two months in. Hope to have suegery in early June as my insurance requires a 90 day supervised doctor program. I have met with the dieticians, program coordinators and nurse practitioners. They are all amazing. I have no doubt in my decision to choose OHSU. I have not met with the surgeon yet but I am leaning towards Dr. Mattar simply because of his extensive experience. He is the Professor of Surgery and Chief of the OHSU Bariatric Services Program.
