I am a medical doctor with an interest in complex chronic conditions, health coaching and preventative medicine. I proudly hail from a family of medics and allied health professionals however I only truly appreciated the immense role of nutrition and lifestyle factors about 20 years ago and it’s made a world of difference to my atopic family. Our family's enthusiasm for education, research and lateral thinking gave me the insight that health is a journey and we need to be continually learning. I'm constantly enthralled with finding out information I didn't know I didn't know and I encourage my patients to come with me on this incredible journey.

We are coming into the age of personalised medicine. I try to stay away from the politics of dogma. What works for you? How do YOU feel? More than anything, I encourage a reconnection with your food, mind and emotions.

Education. Prior to my medical degree (MBBS) from Bond University in Queensland Australia, I completed an undergraduate degree in International Relations with a triple major including French and diplomacy. I have certificates in remedial therapies including herbs, nutrition and acupressure. Post-med, I have completed an Aeromedical Evacuation Course, Helicopter Underwater Escape Training, a Certificate in Medical Nutrition Management an Advanced Certificate in Skin Cancer Medicine.
