Healthcare that treats the individual - not the disease. 

COVID- Please choose whether you wear a face mask, it is no longer mandated.


In the last 2 years, Teleconsultations have been widely accepted as a convenient method of accessing health care specialists and for certain modalities, this removes the physical distance/need to travel. A lot of our testing kits can be couriered to your home;  you then courier the samples back to the lab. 

We can review the results over the computer and create your FxMed recovery plan together, required supplements and botanicals, nutraceuticals can be remotely prescribed and they can also be couriered to your home.




Functional Medicine addresses the underlying causes of disease, using a systems-oriented approach and engaging both patient and practitioner in a therapeutic partnership. Functional Medicine is a personalized, systems-oriented model that empowers patients and practitioners to achieve the highest expression of health by working in collaboration to address the underlying causes of disease. 

Functional medicine is guided by 6 core principles

  1. An understanding of the biochemical individuality of each human being, based on the concepts of genetic and environmental uniqueness;

  2. Awareness of the evidence that supports a patient-centred rather than a disease-centred approach to treatment;

  3. Search for a dynamic balance among the internal and external body, mind, and spirit;

  4. Interconnections of internal physiological factors;

  5. Identification of health as a positive vitality, not merely the absence of disease, and emphasizing those factors that encourage the enhancement of a vigorous physiology;

  6. Promotion of organ reserve as the means to enhance the health span, not just the life span, of each patient.

Functional Medicine views us all as being different; genetically and biochemically unique. This personalized health care treats the individual, not the disease. It supports the normal healing mechanisms of the body, naturally, rather than attacking disease directly.


Functional Medicine is deeply science based. The latest research shows us that what happens within us is connected in a complicated network or web of relationships. Understanding those relationships allows us to see deep into the functioning of the body.


Your body is intelligent and has the capacity for self-regulation, which expresses itself through a dynamic balance of all your body systems. 


Your body has the ability to heal and prevent nearly all the diseases of aging. 


Health is not just the absence of disease, but a state of immense vitality. 


Dr Stefan Billing is in an educational residency with the Institute of Functional Medicine and studying to obtain his AFMCP license in Integrative Health Care. Also a member of the ICHNFM International Collage of Human Nutrition and Functional Medicine and studying the very relevant topic of Chronic Inflammation in Chronic disease
