[I really liked] combining the practical with the theory. The walk on day 3 was excellent, and then combining that with the indoor walking and the practice was a good finish to the course. I thought Gray was very knowledgeable and welcoming, very relaxed and made everyone feel comfortable. (November 2023)


Company Director, Fiit

Gray was helpful in listening to me, giving me feedback, and helping me to further find the voice for my brand. He also gave me good next steps to take. I also feel he is someone I can reach out to as I progress along the way, for which I am very grateful.
