Welcome to Functional Medicine Associates
We are a team of IFM certified practitioners founded by Pete Williams, the first IFM certified practitioner of Functional Medicine in the UK. We are located in the prestigious Harley Street district of Central London. Our team has had many years of experience in helping patients improve their health and well-being through our functional medicine approach.
Our IFM certification means we differ from most other functional medicine practitioners due to our rigorous training and examination. Our certification is recognised as “the gold standard of functional medicine training worldwide”
We recognise that complex chronic disease is just that complex. Quick fix medication for every ill ignores the fact that humans are also complex eco-systems, that need multiple interventions rather than a single bullet approach. We firmly believe that treatment should be by root cause, rather than just by symptoms. Through these experiences, we continually learn from our patient’s challenges allowing us to constantly refine our service to you.
