About Us

Our vision at Myhealth is to establish medical centres in convenient locations that provide the best care, in an inclusive environment.

The first Myhealth Medical Centre opened in Baulkham Hills in 2007 founded by a group of dedicated General Practitioners and led by our Founder and CEO Dr James Liang.

James adopted a very hands-on approach to business guided by two main principles:


which is a Japanese word meaning continuous improvement.


providing patients with the highest level, non- discriminatory medical care and doctors with best and most flexible conditions and environment.

Myhealth has flourished under these two principles and is now the largest shopping centre based medical centre operator in Australia, servicing more than 3 million patients yearly.

* Our GP partner(s) and GPs collaborate with a supportive management team to harness collective professional knowledge to deliver better GP and patient satisfaction. We actively invest in the future of healthcare, performing research and development into health technology, systems and supporting doctor training. At Myhealth, the benefits of growth and development are shared by doctors and patients.

Many medical specialists and allied health practitioners also work within Myhealth to provide holistic comprehensive care to patients including nurses, pathology collectors, physiotherapists, psychologists, dietitians, podiatrists, dentists, and radiologists.

We invite all patients, doctors and allied health practitioners to experience the Myhealth difference.

Our Executive Management Team


Dr James Liang


Dr James Liang is the founder of Myhealth, opening his first Myhealth Medical Centre at Baulkham Hills in 2007. 

His vision was to open quality medical centres across Australia, owned and operated by dedicated GPs, who understand the needs of doctors and patients.

With now over 90 medical centres across three states, James has led Myhealth to become one of Australia’s leading and fastest growing medical centre operators. As a practising GP himself for almost 20 years, he leads by example in providing exceptional patient care and a genuine interest in providing quality healthcare to the community.

Dr Liang is hoping to take Myhealth to another level by developing technology to improve efficiency and service delivery in general practice, and through innovation ensure that our services can be accessed by everyone who currently lacks sufficient medical resources.
