About Functional Medicine Associates

Functional Medicine Associates are a team of dedicated IFM certified practitioners. Founded by Pete Williams, who was the first IFM certified practitioner in the UK, the practice is located in the prestigious Harley Street district of Central London. IFM certification is a badge of quality and commitment, that few have achieved. Certification sets them apart from others who may only be starting out on their road to becoming a Functional Medicine practitioner.

“The Gold Standard of Functional Medicine Training”

The team at Functional Medicine Associates have had years of experience applying Functional Medicine in Clinical Practice. This has allowed us to evolve and continually learn from both our own experiences and our patient’s challenges. Complex chronic disease is just that, complex. For this reason, we use a team approach for each patient. Our experience has shown that this can often be the difference between successful and unsuccessful outcomes. Our strength is in our association.

Our Team

We are all highly experienced in treating many chronic disease states. In addition, we each have our own areas of specialism.

Patient and Industry Testimonials

“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.”

Pete’s patient

“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.”

“Functional Medicine Associates are an outstanding group of integrative clinicians, they have an excellent understanding of the complexities of gastrointestinal 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.”

“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.”

“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.”

“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 Alex, I have been on a remarkable health & wellness transformation, the lessons of which will remain with me. The way in which Alex balances structure & adaptation in the recovery process - addressing physical, mental & emotional aspects - has proved invaluable.”

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

“Despina, it has been great working with you to identify my nutritional needs, I thought walking outside for some sun exposure would be enough vitamin D but clearly testing showed otherwise!”

“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 desserts 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”

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

“I've been working with Pete for just over a year, and he has helped me make some truly significant lifestyle changes. Now in my early 50’s I’ve battled with weight issues since childhood and tried every ‘diet’ going. Pete helped me identify a clearer strategy around improving my health from a systemic perspective. Using a combination of support, insight and expert knowledge, Pete has helped me appreciate that these things take time, as the issues are complex. We ran different tests, including discovering more about my genetic profile which was a very sophisticated and fascinating experience and really helped me change my perspective. With Pete’s patient and professional approach, I have discovered this journey is no longer about weight loss, but about becoming my best self, and living a sustainable, healthful life which does that justice. I have lost and kept off over 2 stone so far!”

“In positive news my bloating feels pretty much under control, I’m not swelling on long haul flights and also not swelling under stress – which is amazing. I’m also going to the loo every day, at least once” So I’m eternally grateful to you for that!”
