About Us

I’m a California girl, living outside of London. While that transition 13 years ago brought with it marriage and travel and excitement, the change of lifestyle, environment (and everything else!) included a fair amount of stress and contributed to some of my health complaints. Ultimately, my research and experimentation led me to FDN, which sparked a whole new passion for wellbeing and then a whole new career for me.

I had a lot of stereotypical hypothyroid symptoms, like weight gain and cold hands and feet, but I also had disproportionately fat legs on my very small frame. I spent years in the gym, cleaning up my diet and visiting every local complementary therapist I could find. I’m one of those who genuinely says, “I have tried everything!”

Eventually, I dragged myself back to my GP, armed with a folder of research, and asked the doctor if he would take a look. As a result, I was diagnosed with an underactive thyroid and Lipoedema, a fat disorder in my legs. Getting that diagnosis from a conventional medical doctor was a long, long road and I want to help others avoid the roller coaster of being told that “nothing’s wrong” when I knew for sure that something was very wrong.

Following on from these diagnoses, I completed my FDN training and have also trained as an AAMET Accredited Certified EFT Practitioner and earned a diploma in Sports and Exercise Nutrition. In addition, I am currently completing a diploma in Life Coaching.

My goal now is to use my enthusiasm and knowledge to help others investigate why they feel like rubbish and address the cause of their symptoms. I specifically focus on making dietary changes and how to navigate that transition. Additionally, I believe reducing stress is key and I integrate EFT into my sessions so that my clients have a tool they can use in between our appointments.

Regaining good health and coping with stress and food intolerances takes grit and patience. Grit Wellness is here to help.
