"Joan runs a busy practice in nutritional therapy and herbal medicine in Dalkey, where she combines nutritional support with medicinal herbs to optimise healing. Her teaching emphasises nutritional and naturopathic approaches to chronic diseases, and her clinical experience is a valuable resource for students. She is an expert on the digestive system and its relation to immunity, and the interconnectedness of body systems.
"Joan trained initially at the Institute of Optimum Nutrition and then went on to gain a BSc. honours degree in Nutritional Therapy at the University of Westminster. She followed this with a two year post graduate diploma in Herbal Medicine and is now practising in Dalkey, Dublin as a Medical Herbalist and Nutritional Therapist.
"She is a member of the British Association for Applied Nutrition and Nutritional Therapy, Nutritional Therapists of Ireland, National Institute of Medical Herbalists and Irish Medical Herbalists Organisation.
"Joan has a particular interest in the areas of stress, anxiety, adrenal fatigue and other chronic health and digestive problems and regularly attends medical and nutritional seminars. Her interest in environmental medicine has led to involvement with the anti-fluoride movement in Ireland. She believes there are connections between fluoride uptake from tap water, low iodine status and increasing rates of thyroid disease. Joan, a keen gardener, is interested in growing her own food and using foods from the wild and enjoys sharing this interest with students."
