Our Team

Mr Michael Booth

Our Surgeon – MBChB MBA FRACS

Michael is highly experienced in open and laparoscopic surgery and has over the years performed more than 5000 laparoscopic operations for gallstones, hernia, reflux and weight loss. He has been lucky to straddle the era when major abdominal surgery transitioned into major laparoscopic surgery giving him skills in both open and laparoscopic surgery. He is also an experienced endoscopist.

He also has an appointment at North Shore Hospital (Te Whatu Ora Waitemata) and over the years has trained many upper GI and Bariatric Fellows who are now practicing consultants in New Zealand and overseas. He is a member of a number of Surgical Societies.

He has lead Bariatric clinical research at North Shore including Randomised Controlled trials for the treatment of obesity and Type 2 diabetes as well as antireflux surgery. He is particularly interested in the long term outcomes of surgery and has published on this.

We need to look at our outcomes to look forwards in our practice.

He is an Affiliated Provider with Southern Cross Health Care

Dr Chaey Leem

Our Physician

Chaey Leem is a NZ-trained medical graduate from the University of Otago. He aspires to become the first bariatric physician in New Zealand – a very new field of medicine which is currently under-recognised.

After graduation, Chaey has worked in a wide range of surgical-based rotations including his time with Michael Booth, which greatly sparked his interest in helping patients with obesity. He is SCOPE certified, an internationally recognised certificate in obesity management. As a bariatric doctor, Chaey is interested in providing an individualised, patient-centred treatment plan.

He is looking to support patients throughout their entire journey, from before surgery to many years after surgery too.
