We are proud to have helped many patients on their journey to recovery and have worked with many inspirational people in healthcare. Here is what a few of them have to said about us along the way.

Functional Medicine Associates is joined up medicine and healthcare at its best


Thanks to Alex my 5-year battle with IBS symptoms is finally over. I feel amazing!


I was referred by a friend to Pete after I was diagnosed with breast cancer. Although I was getting the best possible treatment that private medicine could give me which involved chemotherapy and radiotherapy, I wanted to do everything possible to understand how my lifestyle influenced my condition. After all, my life was at risk and this is where Pete and Functional Medicine Associates became involved. I have been helped at every step of the journey to good health. Pete and his team have explained the science, the blood tests, the genetics, the food and exercise and how to apply it practically on a day to day basis. I am in remission and feel great!

Since working with Deirdre, I have experienced huge transformations in my health. When I arrived at her desk, I was experiencing insomnia, digestive issues, fatigue, brain fog and low mood. Through some testing we established there was candida overgrowth and hormonal imbalances and over a few months with Deirdre’s personalised protocol I got my health and vitality back. Deirdre has a very relaxed and friendly manner and was there to answer questions and provide support at every step of the way. I am grateful to her for where I am now and for her encouragement to address the root cause of the issues and take a lifelong outlook to health and happiness.


My doctor, nutritionist and personal trainer all rolled into one. Functional Medicine Associates are the perfect answer to the ill effects of 24/7 big city living.

My doctor said there was no cure for Fibromyalgia/CFS. There is, it’s called Functional Medicine. I feel so much better with Functional Medicine Associates treatment.


Despina, I never thought I could live without all my sugary treats, and with your help I have learned how to change recipes to make gluten free and dairy free deserts and swap sugar for dates and bananas and all sorts of new and innovative alternatives! It has been a fun journey and my waistline is thankful


Our Industry

The Gold Standard of Functional Medicine training

The Institute for Functional Medicine

We have worked with Pete and his Functional Medicine Associates, for several years. They are a group of clinicians who have an excellent understanding of genetic testing, but more importantly how these tests fit appropriately into the bigger picture of their patient’s programmes. I highly recommend them.

Dr Danny Meyersfeld

Pete and I did much of our Functional Medicine training together, he and his team “Functional Medicine Associates” are my go-to recommendations for patients in the UK

IFM certification is a badge of quality and commitment, the relatively few who have achieved this accreditation will have spent much time, as well as a significant financial commitment in participating in this rigorous post-graduate training. It sets them apart from any others who may only be starting out on their road to becoming a FM practitioner. I have known Pete Williams for many years, he has an excellent knowledge of Functional Medicine and how to employ it. However, the complexity of clinical conditions requires the need to utilise this knowledge and skills of other similar trained professionals. The team that Pete has brought together, all of whom are IFM certified is an excellent initiative; recipients, whether they are patients or practitioners in education – can be assured of the highest quality, knowledge, and team work.

Functional Medicine Associates are an outstanding group of integrative clinicians they have an excellent understanding of the complexities of gastro-intestinal disorders but also the potential systemic health issues that may accompany. They will regularly discuss patient results with our consultants and I highly recommend them.
