Dr Darwin Luc - Dentist at Somerville Dental Health

Dr Darwin Luc completed his dental degree at the University of Melbourne, graduating with Honours.

Darwin is a member of the Australian Dental Association and is an avid attendee of continuing professional development courses in order to stay up to date with the latest advancements in dentistry. This ensures that his patients receive the best possible evidence-based care available today.

He enjoys practising all aspects of general dentistry, with a special interest in:

He is passionate about working with patients with a comprehensive approach towards achieving their individual oral health goals and attaining a healthy smile for life.

In his spare time, he enjoys spending time with his wife and 2 daughters. They love travelling and sightseeing, whilst experiencing different culinary delights. He also enjoys being a handyman around the house, and is always so close to finishing the home renovations until he discovers a new project!


Dr Ross Churcher

Dr Ross Churcher - Dentist at Somerville Dental Health

Dr Ross Churcher has been a part of Somerville Dental Health since 1981, originally with his older brother David. As a result of some strong (and at times unpleasant) memories of his experience of going to the dentist as a child, Ross is determined to make his patients’ dental experience as gentle and pain-free as is possible.

Ross is a member of the Australian Dental Association. He enjoys all aspects of practice, with particular interest in:

  • cosmetic/aesthetic treatment
  • orthodontics
  • implant dentistry.

Over his career, new procedures have constantly been evolving. This has made being a dentist a very satisfying and challenging profession for Dr Churcher.

Ross still finds his greatest enjoyment is from assisting people to take charge of their oral health, catching problems early and over time, creating a sound and stable level of dental health. For most people, once this is achieved with high-quality restorations and with good home care and diet, only occasional minor maintenance is usually required. He finds this especially satisfying when it has allowed a formerly nervous patient to overcome their fear, gain confidence and trust so as to then come along happily to maintain their health year after year.

Outside of work, Ross is, with his wife, a keen cyclist, snow skier and ocean sailor and the proud father of 2 lovely daughters.
