Private Functional Medical Clinic

Had Enough of doing the Same Things and getting the Same Outcomes?

The clinic’s aim is to use 90 minutes of professional medical advice to help clients influence a lifetime of nature and nurture, for a meaningful outcome within 2-3 months. That’s no small undertaking, so what will clients need to do to play their part? There's an initial investment of time and money to create change e.g.

  • While the cost of living may even reduce with modified nutrition & habits, there's an interim change in lifestyle & habits that must be funded & resourced

  • Lab Testing reduces trial and error.  With only 15 contact hours per week, the clinic needs to be targeted

  • Supplements may be used therapeutically, or to address a deficiency

  • Referrals may be required to address addictions or plug other holes

How useful is generalized Health Advice published in the Media?

Paraphrasing a recent lecture by Prof Luis Vitetta, the assumption of all medical studies is that humans are genetically the same; this calls into question the conclusions of these studies.
