Dr Phil Parker

Principal Doctor

“Good health comes from addressing physical, mental and emotional wellbeing.”

Dr Phil is a general practitioner that brings broad life experience to his work.

Dr Phil grew up on a farm, where he learned of the mental and physical challenges facing the rural community. He studied horticulture before moving on to become a high school teacher where he taught agriculture and science. This ignited his passion for teaching and developing the next generation, a passion he continues throughout his work as a GP.

He spent 28 years in the Australian Army, where he completed his medical training and has served in both full and part-time roles. In 2012 he deployed to Afghanistan as the Senior Medical Officer in the province of Uruzgan and coordinated Coalition forces’ medical care and mentored senior Afghan military, police and civilian health staff. In this role he witnessed the traumas of war and understands the difficulties that veterans endure in trying to move forward with their lives.

Since leaving the Army in 2015, Dr Phil moved into private practice as a GP and founded Green Tree Medical in 2019. He relishes his role as a GP as it offers an opportunity to make real connections with people and to support them through the challenges of life.

As a GP, Dr Phil remains committed to the care and support of veterans and their families.  His military experience and knowledge have seen him take up roles associated with veterans’ health.

He is a Consultant General Practitioner with the Anzac Support Centre, where he provides consultation to practitioners Australia wide about a wide range of veterans’ health care issues.

He is also the Gallipoli Medical Research Foundation’s GP Ambassador where he provides advice about PTSD management within primary health care.

Dr Phil is also an experienced and qualified medical educator and has worked extensively with doctors training to become general practitioners. He brings his passion for education to his role as a GP, ensuring patients understand their health issues and treatment options.

Dr Phil enjoys all aspects of general practice and is especially committed to the health of those patients with multiple medical conditions requiring an extra element of personal care and support.

When not in the clinic, Dr Phil is a team sports tragic, a proud and committed dad and likes to travel.
