Dr Sarah Davies

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 Functional Nexus 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, a Health Coach, a psychotherapist and Journey Practitioner.

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.

Qualifications: MBChB, MRCGP, IFM Certified Functional Medicine practitioner
