Meet our Coaches
Dr. Kevin Willis
Kevin Willis, PhD, is a sports psychologist who helps athletes, coaches, parents, organizations and business leaders perform under pressure. His work centers on purpose, awareness, and mindset, the three levers that drive real, lasting improvement in competition. He translates that same psychology into the business world, helping entrepreneurs and executives build resilience and get more done with less friction. Kevin also tracks how digital habits and social media are reshaping attention and confidence in today's competitors, and builds that reality into the strategies he teaches. He pairs psychological research with practical, usable tools, so audiences leave with something they can apply the next day, not just something to think about. Catch him on NHL Radio - Sirius XM
