Welcome to Functional Medicine Associates

We are a team of dedicated Institute for Functional Medicine certified practitioners.

We have had years of experience applying Functional Medicine in clinical practice and this has allowed us to evolve and continually learn both from our own experiences and those of our patients.

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 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.

We firmly believe that treatment should be by root cause, rather than just by symptoms. Through our experiences, we continually learn from our patients’ challenges allowing us to constantly refine our service to you.

Providing a safe space for you to heal

The nature of Functional Medicine dictates that it is not a quick fix solution but rather a comprehensive and complex approach and that in order to see results, an initial commitment of 3 months is highly recommended.
