My Story

My journey to becoming a nutritionist and personal trainer began many years ago when I realised that a balanced diet is an essential part of spiritual and mental health, and physical fitness. After trying different diets such as raw food, vegan, vegetarian and others I became aware of the nutritional gaps in most modern diet plans, including the lack of some essential vitamins, minerals, proteins and other compounds which are necessary for good health and longevity.

After sharing this knowledge amongst my family and friends I noticed significant improvements in their appearance and overall well-being. This experience motivated me to study and gain a diploma as a nutritional therapist and personal trainer and start my business OMnutritionist. The goal of all my training and advice is to make you understand your body and its needs, to get you back in to balance with yourself.
