Nutrition Team

Kirsty Cullen

Director of Nutrition – Kirsty Cullen, BA (Hons), DipBCNH, mBANT, CNHC

Kirsty worked within the executive recruitment industry for 10 years, operating at senior management level. Her interest in nutrition began as a consequence of health issues experienced by her daughter. Having investigated ways in which to support her daughter’s health, Kirsty was inspired by the improvement in her daughter’s condition following the application of nutritional therapy principles and dietary change. This proved to be a turning point both personally and professionally and Kirsty made the decision to pursue a career in nutrition, later graduating from BCNH – UK College of Nutrition.

Kirsty joined the team at the Optimum Health Clinic in 2011- having experienced her own mother’s struggles with M.E., she was inspired by the specialist focus of the clinic.  In addition to her work with the Optimum Health Clinic, Kirsty runs a private clinic in Shropshire, seeing clients with a wide range of health concerns. She is also passionate about educating children and runs classroom-based workshops for primary school children, to promote a greater understanding of the benefits of healthy eating. Kirsty’s approach is both empathetic and encouraging – she strongly believes in equipping her clients with the ability to take control of their own health, via an improved understanding of the impact of nutritional balance and dietary change.

TammyTammy Hubble, DipCNM, mBANT, rCNHC

Tammy started her career in management and was definitely in the ‘work hard, play hard’ category.

Whilst having a career break to enjoy her two young girls, she was diagnosed with breast cancer and went through every surgery and treatment possible to ensure she would be sticking around for them. After taking stock of all that had happened and her family medical history (stress, depression, alcoholism, arthritis, cancer) she decided it was time to make some changes!

Through better nutrition and supplementation her post treatment fatigue faded away and she started to feel herself again, so was inspired to train as a Nutritional Therapist to help others with chronic conditions improve their health.  Although Tammy has seen clients from all walks of life, she has specialised in supporting patients through cancer treatment, fatigue and stress related conditions. She likes to think of herself as a health detective, taking guess work out of supporting your journey back to health and most importantly helping you get the most out of life!

Being an avid home cook and having managed many a restaurant, she has been known to hold healthy cooking workshops – so in her spare time is usually found in the kitchen (creating recipes), drinking herbal teas (slightly addicted) or exploring new places on foot.

Karen Preece Smith, MA, BA(Hons), NTDipION, mBANT, CNHC

Karen began her working life as a Lifestyle journalist. For several years she worked in Fashion- an industry far more concerned with outward appearance than inward health. Her awareness of the benefits of nutrition changed in her mid-twenties when she embarked on an intense three-month yoga teacher training programme in Hawaii. The tough physical demands of the training made a balanced nutritional programme essential to success. On realising the advantages of correct nutrition, Karen became fascinated at how the food we eat can play such an integral role in how we feel, in terms of physiological, emotional and mental health. A desire to help more people discover the nutritional science behind how to support underlying imbalances in their body led Karen to the decision to re-train as a nutritional therapist. She studied for a three-year diploma in Nutritional Therapy at The Institute of Optimum Nutrition and has since set up private practice in London and more recently in Cheltenham, where she now lives.

Karen has worked with a number of clients who have a variety of chronic conditions, including stress and digestive health-related concerns. In addition to this, Karen has run numerous nutrition workshops to help people understand the vital role nutrition can play in their everyday lives. She is known for her empathetic style of relating to clients and her enthusiasm for discovering the root cause of a problem.
