Welcome to the gold standard of functional medicine care.

Functional Medicine Associates is a team of IFM certified practitioners with a practice in the prestigious Harley Street district of London, operating nationally and worldwide.

What is Functional Medicine?

“A new way to heal”

Functional Medicine Associates was founded by Pete Williams who has over 20 years of experience applying Functional Medicine in clinical practice and is one of the leading figures in Functional Medicine in the UK.

2020 was ‘the year of the pivot’ for many businesses so rather than restrict our service offering to in-person consultations you can now take advantage of FMA’s expertise either in person or online, from anywhere in the UK and beyond.

“I think anyone with the right attitude and correct guidance can heal themselves. They just need an operating system to put all the bits and pieces together. That’s Functional Medicine”

Pete Williams





Pete Recommends

We appreciate that not everyone can be treated by us and hence "Pete Recommends" is about sharing our expertise to a wider audience.

Decades of experience have helped us to understand what works and what doesn’t. Whether its products, tests, health strategies or day to day expert advice, "Pete Recommends" is an advice centre from our expert group of functional medicine practitioners.

Over the next year we will increasingly populate this page and we would love you to join us on this journey.
