Our GPs practice functional medicine, a discipline focused on treating the underlying causes of disease, rather than symptoms alone. With a strong knowledge of how to combine complementary and allied healthcare, our healthcare professional team are at the forefront of functional healthcare.

This collaborative and integrative approach ensures you receive multiple treatment modalities and the collective knowledge of a dedicated team. 

Combined GP and naturopath consultations

Our integrative GPs and naturopaths work closely to share their knowledge of biochemistry, nutrition and herbalism, providing a greater platform for understanding the causes of your health issues. Combined GP and naturopath consultations are available in our Byron Bay medical clinic and Australia wide via Skype.
