Care Team

Our team of nurse practitioners and physician assistants are 100% dedicated to bariatric surgery and assist the surgeons in the office, operating room, and hospital. Unlike residents or fellows in an academic program, they do not rotate in and out of the service, patients see them regularly throughout their journey.

Insurance Coordinators

Our center is fortunate to have a team of in-house insurance experts—Most insurance plans cover bariatric surgery. Still, there can be some nuances in what each company requires before your surgery is authorized. Our team helps ensure that your insurance will cover your surgery and that the insurance paperwork is complete before your surgery.
