My Life mission

To Empower

I see my life’s mission to present the amazing influence our mind has, on the world we create for ourselves, in a way that empowers everyone that I interact with. This certainly includes every aspect of our being, including the area of our health.

To Inspire

My work as a surgeon might make it seem that I deal with only the physical or bodily aspects of disease. However this knowledge has helped me empower my clients with a unique tool which helps with their “inner healing”- a factor which can have the most powerful influence on outcomes. By being in harmony with ourselves and our surrounds, each one of us can experience success in whatever we do – for the common denominator of success in any field is “being happy and at peace in the moment”.

To Serve

If it is true that Knowledge is Power, then Knowledge about the Self is Self Empowerment. I believe we were all sent on our Earthly journey to fulfil a mission and to lead a Fulfilled life at the same time. That’s indeed what makes the journey more memorable than just reaching the destination. I look forward to sharing the road with you on this journey.

Dr. Arun

I asked my master “How can we make a difference in this world?"
"One life at a time” he replied

You can change your world by changing what you feed your mind and your body.

He is also a Yoga and meditation teacher and along this journey, has nurtured a very keen interest in mind, body and gut connection, which he incorporates in his practice.

My Services


I feel privileged to be able to serve my patients and be able to hopefully make a positive change in their lives. I have practiced surgery now for over 25yrs and never in one day of my life have I ever regretted the position I am in. I am fortunate to have an amazing team that supports me and allows me to do the work that I am so passionate about.

Army Officer

In March 2022 I was appointed into the Royal Australian Army as a General Surgeon (Reserves).Being the son of an army officer, I believe the desire to serve the country that I call home, was in my DNA. I had to go through some very rigorous training which hurt my body but also my ego. Ultimately there were valuable lessons that I needed to learn to have the privilege to serve in the royal Australian army and uphold its values.

Researcher and Speaker

Research and scientific inquiry is the basis of growth and development in any field of work. Although I am not heavily involved in laboratory based research, clinical research has always fascinated me. I’ve had the opportunity to collaborate and partner with individuals and organisations on various research projects that I am working on.

I love speaking and sharing my understanding of medicine, surgery and concepts of mind body connexion and how it translates to our health and well being.
