My Background

This website is an avenue for communicating with my patients. I keep very up to date with health issues, especially to do with aging and hormonal problems. I will share the interesting bits with you. I have a daily blog dealing with health issues. You can subscribe to this free service by entering your email address in the space provided.

I am a GP working in Caboolture, Queensland. I have a special interest in natural hormone treatments, also known as body identical, and sometimes as Bio-identical hormones. The name derives from the fact these  hormones are identical to the hormones we produce naturally. I am not an endocrinologist, or a Gynecologist, and have never claimed to be one.

I have been using these hormones for the last 25 years, and have treated nearly 5000 people with them.


I have a MB Bch,(Bachelor of Surgery and Medicine).  I also have a Diploma in Obstetrics, obtained from the Royal College of Obstetricians and Gynecologists. As well I have a Diploma in Tropical Medicine and Hygiene, obtained at the Witwatersrand University, South Africa. I am a Fellow of the Royal Australian College of GP’s.  Over my lifetime I have delivered over 1500 babies, an achievement I value highly. Some of those I delivered are now my patients.

Books written:

Having studied diet, lifestyle, health and positive attitudes, I was frequently asked as to why I did not share this knowledge with others more widely. So with the encouragement of my wife, I would get up at 4 am to research and write “Live Well Over 100.”  The first edition of 5000 sold out very quickly, so more study and earlier am starts led to the second edition, which was a lot bigger and more in-depth. The print run of 20,000 sold out fairly quickly as well. I was invited to speak at various health related conferences, something I really enjoyed, as I got to meet people from various parts of the world. I spoke in conferences in New Zealand,  Singapore, Philippines, South Africa and Australia of course. Unfortunately, the book is now out of print, and is no longer current as it was written over 15 years ago.

Live Well Over 100

While touring New Zealand and giving talks at various venues, I met Michail Borrisenko, who had a great interest in Colostrum, and the many health benefits thereof.  Michail and I coauthored  “Microbe Apocalypse- Man Vs Microbe'”.  Michail Borrisenko, is chief scientist, Institute of Colostrum Research,  New Zealand.

Microbe Apocalypse

I wrote “The Medical Vitadiet”, which has sold over 25,000 copies to date. This deals with the benefits of the low-calorie diet to produce weight loss. At one stage I had 5 weight loss clinics in Queensland, with very successful results. Having decided to move on to other aspects of health, I sold the business, but allowed the new owners to continue to use the book I wrote as part of the program.

Women’s Hormones.

Some of the motivation for this web site is to present the medical evidence and research to reassure men and women about the science behind what I do and to refute some of the misleading information   about Natural (Body identical,Bio-identical) HRT.
