Our Doctors

At Gastric Balloon Australia, your weight loss journey (and all of the care surrounding it) will be co-ordinated and managed by one of our 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 physicians so take some time to meet them below.
