Specialist in health and nutrition

I'm an experienced, highly qualified Registered Nutritional Therapist in Weybridge and Cobham, Surrey (having completed my degree in 2006) with extensive further training in Functional Medicine, having passed final exams & fully certified in 2024. I have helped hundreds of clients, from burnt out city workers to tired mums, parents who are struggling with their child's health or eating behaviours to elderly people with multiple health problems and medications. I'm also mum to two great (mostly!) boys, now 16 and 14 years old, one of whom taught me lots about dealing with a fussy eating & problem sleepers!

I love working with children and teenagers, their honesty and how they always surprise me and sometimes their parents with what they have to say about their health problem or why they are not keen on eating certain foods. My goal is always to gain their trust and get them engaged in the advice I'm giving so they are keen to put it into action! I find most children love to hear about how their bodies work and why what they are eating might be helpful or not helpful, all with a healthy dose of fun & humour! However, I know that some children will not find it easy to make dietary changes and I'm realistic that few families manage to have a perfect diet all of the time including my own family!

Help with specific conditions?

My focus areas include digestive issues, enhancing immunity, and the often-overlooked nutritional impacts on brain function, mood and behaviour in children.

Clare's advice was brilliant

"Clare's consultation was extremely thorough and she immediately identified key issues that the doctors and I had overlooked. My daughter has also seemed far more resilient to bugs and viruses. Thank you Clare, from one happy child and one VERY grateful mum!"
