John Knowles

“The Goalie Whisperer”

With over 10 years of female athlete coaching experience from the youth to the collegiate level, in multiple sports, John brings a unique perspective and approach to goalkeeper development. As a certified coach for USA Lacrosse, US Soccer, and USA Hockey, he has the knowledge to customize your learning experience. As a certified mental performance coach, he can take your game to the next level by helping your master your inner game.

John’s coaching philosophy is the foundation of the Deny Goalkeeping philosophy:

“I build significance into the lives of the athletes I coach by creating an engaging athlete-centric environment focused on the development of life skills for the “complete” student athlete. I create a positive, challenging learning environment where individuals can play with personality, celebrate their uniqueness, and grow in confidence. I accomplish this through the teaching of the individual and team skills required to be successful while nurturing the enjoyment of the game by maintaining a proper balance of process, results, and perspective.”

John is currently the goalie coach for both the Roberts Wesleyan Redhawks Women’s Lacrosse, Women’s Soccer, and Women’s Field Hockey teams, and the former Program Goalie Director for the Aces Elite Girls Lacrosse club in Rochester NY.

“John is a sought after goalie coach of many sports in the Rochester, NY area. An athletes mental game is finally a focus and he works to build a strong foundation of confidence and coping skills. What makes him the best of the best is his reputation to develop goalies by preparing them mentally as well as physically.”
