Dr Nicholas Williams is general surgeon specialising in weight loss surgery, upper gastrointestinal and endocrine (thyroid, parathyroid, adrenal) surgery.

Nicholas completed his medical degree at the University of New South Wales (UNSW) in 2001 and, in 2009, became a Fellow of the Royal Australasian College of Surgeons in general surgery.

He then undertook a fellowship in hepatobiliary-pancreatic surgery at Royal North Shore Hospital, before pursuing a further fellowship in endocrine and advanced laparoscopic upper GI surgery at Mexico’s Salvador Zubirán National Institute of Health Science and Nutrition.
