"Just wanted to take a moment to express my gratitude to Jack and Greenbelt for the best tennis coaching I've ever had. I've worked with Jack on a weekly basis for nearly a year and a half and his teaching has lifted my game, big time. He coaches not only the techniques but the tactics and strategy behind the game.

Jack is thoughtful, patient, thorough and amazingly adept at accomodating a particular player's temperament and playing style. A gem of an instructor you have there.

The only reason I'm not continuing my weekly lessons with him is that I'm leaving the country! Cheers. " - Bob Wood
