Dr Rosie Walwyn

MbchB, MRCPsych and Afmcp
Working in the psychiatry department, Dr Rosie noticed how much health was siloed.

The Clinic Story

With a longstanding active interest in nutrition, Dr Sarah began to look for more natural and non-drug based ways to help herself and her family with their health problems. After seeing the benefits of the functional approach in practice at home and with her NHS patients, she decided to train in Functional Medicine.

Dr Sarah is one of a small number of fully certified Functional Medicine doctors in the UK, and combines her experience from over 18 years as an NHS doctor with her training in Functional Medicine from the prestigious Institute for Functional Medicine based in the US.

The original Functional Medicine clinic was opened in 2016 and has grown steadily. Dr Sarah now leads a Multi-disciplinary team including fellow Functional Medicine Practitioners Dr Michael Cameron, Dr Nirusa Kumaran and Dr Rosie Walwyn and Consultant Endocrinologist Dr Clementina La Rosa alongside expert Nutritional Therapists, Kelli Tassi, Laura Johnson and Dalbinder Baines and a Health Coach, psychotherapist and Journey Practitioner Karen Butler. The clinic doctors use their knowledge of general medicine alongside their training in nutrition, genomics and lifestyle medicine to help a wide range of patients with chronic health conditions to restore and optimise their health.

The Clinic passionately promotes the importance of nutrition and lifestyle in shaping and optimising health -preferring this approach over medications to mask symptoms wherever possible. We have many successes treating patients with autoimmunity, thyroid problems, chronic fatigue and many other issues using these techniques.

After seeing the amazing benefits of the functional approach in practice both at home and with her NHS patients, she decided to train in Functional Medicine.

The clinic views educating and empowering patients to take control of their own health as essential for success. It is often the efforts of the patient themselves which has the biggest impact when working in this field.

We advocate the use of advanced nutritional and hormonal screening tests, to inform our holistic Functional treatment plans. Using cutting edge diagnostics we drill down to understand the root causes of chronic disease.

Our practitioners continually work to expand their knowledge and understanding by joining together as a team and with like-minded practitioners from all over the world in continuing professional development.

Health Coach
“The journey towards optimal health has to start from where each of us finds ourselves now. Change is not always easy, but once the benefits are felt, the encouragement to continue gathers momentum.”

— Dr Sarah Davies

“Dr Sarah is the number 1 functional medicine doctor in the UK. Sarah’s skill and ability give patients clear guidelines, tools and directions. I have witnessed how patients go from feeling hopeless to optimal health and thriving at life.”

Joanne Grobbelaar, Business Coach

“Dr Sarah is that person who is able to give answers and get to the bottom of my issues. I have a clear understanding of what’s happening and what’s going on and more importantly how I can help myself to get better. Since seeing Sarah my sight has returned in one of my eyes and my joint pain is very minimal. I feel like I’ve won the lottery!”

Mrs CP

“For the first time in my life I felt really ‘heard’ by a doctor, rather than my symptoms being dismissed. I felt like I had found someone who could actually care for me, as me, as a human being and not just isolated body parts or medical conditions.”

Mrs CL, Switzerland

“I want to express my thanks and gratitude to Dr Davies for her guidance, knowledge and insight which has helped me help myself. A truly exceptional Doctor who has given me my life back.”

Mrs AB, Stockport

“The fact that I now have the knowledge about my own health is reassuring and the ability to discuss concerns/results with a health professional at length really was beneficial. Having someone to listen made all the difference to me and Dr Sarah’s approach was uplifting in itself.”

“I came away feeling that there was hope, I’d been believed and listened to.”

54 year-old female

“As a qualified GP and Private Functional Doctor, I trust her because she is an incredibly knowledgeable expert who not only cares but actively listens and then looks for the causes of your disease rather than simply silencing symptoms.”

Mrs DW, Stockport

“My case hasn’t been very straightforward at all, and she has done amazing problem solving, with my interests and wellbeing always in mind. She has often reassured me that we will ‘keep looking’ – and this has really paid off. I am extremely grateful for this.”
