    “I was looking for a nutritionist who was research-based and had applied their own expertise to all the nutrition information out there. Gavin did this brilliantly for me. He spent time to understand my priorities and goals and customised his recommendations to best fit my needs. I’ve already had some great success based on his advice and I’m confident he would be able to apply his expertise to achieve excellent results in any sport or lifestyle. Couldn’t have asked for more :) “
