About me

I am a degree qualified Registered Nutritional Therapist (BSc Nutritional Science, First Class Hons) and health coach, offering personalised 1-2-1 consultations and group workshops.  As a competitive runner and GB-age group long-distance triathlete, I have a specific interest in sports and performance nutrition adopting a functional (holistic) approach.

I am passionate about empowering my clients to make long term dietary and lifestyle changes through education and support, helping them understand the impact that their diet and lifestyle has on their health and performance.  I work within the 'functional medicine model' which means I will look at your body holistically, including genetics, environment and lifestyle to reach the root cause of your symptoms.

As well as offering tailored-performance consultations and packages for athletes, I work along side other clients to support them with long-term weight loss, blood sugar management, chronic gut complaints, auto-immune conditions, hormonal imbalances and unexplained fatigue.  Regular support outside consultations via skype/phone/email is an integral part of any package alongside behavioural coaching to help change long-term ingrained habits where necessary.

I see clients in both London and Hertfordshire and offer consultations via Skype for follow ups or for first consultations where logistics make it difficult to do face-to-face. I work frequently alongside consultants and GP's where appropriate to ensure the best care possible for you.

Please email me to arrange a complimentary 15 minute call to chat to about your health goals and how I can help you.

Nutrition topics

Information about health conditions (*)

Nutritional therapy can help enhance the well-being of individuals diagnosed with serious medical conditions, but should not take the place of medical treatment and advice. If you have been diagnosed with - or suspect you may have - any of these conditions, please speak to your doctor before starting nutritional therapy or making any major changes to your diet or lifestyle.


Please see my website for details on packages offered or contact me directly by email as above.

Wheelchair user access

Wheelchair-accessible premises should have step-free access for wheelchair users and individuals who are unable to climb stairs. If a nutritionist's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the nutritionist to discuss the options available.

Under the Equality Act 2010 service providers have a duty to make reasonable adjustments to ensure that individuals with disabilities can access their service. You can read more about reasonable adjustments to help you to access services on the CAB website.
