"I worked closely with Don and found him to be a highly effective leader and manager. His ability to get the best out of people and his capacity to build strong teams working with a common focus and goal is a real strength"

"Don's support, and that of GTG has assisted me immensely over the years in achieving my goals of becoming an Australian Champion. I would highly recommend GTG to anyone requiring coaching or facilitation to help them as individuals, or their teams, in reaching the next levels of high performance."

"I have known Don for over 10 years and included deployment to Afghanistan in 2012. I can personally attest to his professionalism, dedication, and ethical leadership standards. I provide this testimonial on behalf of all soldiers he has had contact with, noting that he could easily obtain hundreds of individual endorsements. He is the exemplar of a Leader and cannot endorse him highly enough"

"I have known Don for an extensive period and can attest to the high standards of ethical leadership he espouses. His development of the WAXTM methodology for decision making, coupled with his ability to break complex problems into tacit actionable items is an asset to any organisation or individual looking to improve their congruence withi"

"Don was my first Officer Commanding within the Infantry, and he was also the one that I would rate the highest. His natural care for his people is unmistakable and rare. His leadership indeed inspired me to become the best version of myself, and his ongoing support to me (beyond what some would call his tenure) has assisted me greatly in my mindset. His coaching on high performance has helped me in my pursuit of becoming the Australian Champion, representing Australia to compete at the World Championships and become one of the most recognised fighters in the world in my sport – with over 200k followers."

"Don has graciously volunteered in my club, with his knowledge and support to my boxers, in the form of group facilitation and individual mindset preparation for competitions. The change that I have seen in my team is marked and significant. Not only in how they are training and competing, but how they are now carrying themselves as engaged members of their local communities. I highly recommend him as a facilitator and as an individual helping good people."
