Our Doctors

Your weight loss program is coordinated and managed by one or more of our experienced and compassionate specialist doctors.

Our doctors are world leaders in non-surgical and surgical bariatrics (the branch of medicine which deals with weight management and obesity). Your initial consultation, procedures, and many of your regular post-procedure follow-ups will all be one-on-one with one of our specialist and bariatric physicians, so take some time to meet them below.
