Our Bariatric Program is a unique multidisciplinary program encompassing every component needed for successful weight loss, including highly experienced bariatric surgeons and physicians in Oklahoma.
While other programs may refer patients to dietitians, exercise physiologists and other qualified professionals for assistance with their pre- and post-operative plans, Weight Wise patients have the benefit of meeting with a cohesive team that works together on a daily basis. We have the same goals, philosophies and sense of teamwork necessary to help patients through the entire “life change” process.
