Professional instruction for athletes of all levels


In addition to private individual instruction and small group instruction, we also offer team and league instruction, coaches clinics and camps, college/pro tryout preparation, off-season/preseason conditioning, strength training and more.


Aside from physical training, we feel that it’s in each player’s best interest to develop self-esteem, confidence and sportsmanship. This is not only our moral obligation, but will prove to help the athlete, both in mindset and performance, throughout his/her athletic career.

John T. Denny

Professional Coach, Consultant


John played baseball in Little League, high school, played baseball and football for the University of Arizona on a full college scholarship and played professionally with the Seattle Mariners.


John was afforded the ability to train with major league athletes, coaches, trainers and scouts growing up. He learned the techniques that helped him to succeed in college baseball and play professionally.  Those techniques, coupled with knowledge he gained in his own professional career and an outstanding work ethic, are what he passes on to his athletes now. As he stays connected with current coaches, scouts and agents, he can give his athletes the best guidance in their baseball careers.


John's patience, positive attitude and his experience in all aspects of the game- from hitting, pitching and fielding to being scouted and getting college and professional exposure allows him to help athletes of all ages succeed and bring their game to the next level. John coached for "24 Hours for Africa," the world's longest baseball game, for charity and sits on the advisory board of the Florida Collegiate Summer League.
