I am very passionate about helping people with their health journey. My medical background began with a nursing degree, specializing in maternity nursing. From those early years I had always held an interest in nutrition. My experiences revealed that there are also psycho-emotional roots of disease. I completed a degree in psychology. I have worked in many hospitals in many different fields of medicine. Those opportunities have given me an appreciation of the benefits of orthodox medicine, but at the same time ignited my passion for healing the natural way. After completing my studies in naturopathy/nutrition in 2004, I have been working towards further blending the best of medicine with the best of Nutrition with specialised interest and training in the field of Nutrigenomics
