Weight Loss Victoria comprises our two specialist surgeons, Mr Geoff Kohn and Mr Dean Spilias. It is the weight-loss surgery arm of Melbourne Upper GI Surgical Group.

We have extensive experience in the full range of weight loss options, and we therefore believe that we are well-positioned to tailor the right management plan to the right patient.
