Having been a collegiate athlete and high school football coach for many years, Kris decided to join with a business partner, Chris Falcon, and create an entirely new business built around fitness and performance. Kris’s passion has always been teaching and coaching to help connect people and build relationships. That energy is now fully focused on building the WIN community.
