The Story

John loved platform tennis. As a busy professional and family man, “paddle” provided a critical competitive outlet to his life. The problem was, he just couldn’t get enough training time to improve his game. Further, when he was free, it was often outside of normal hours. An engineer and builder to his core, he rigged up an improvised ball machine at his club. It turns out, he wasn’t alone in looking for ways to up his game. Players across all skill levels would stop him after his practice sessions and ask where they could buy their own machine.

It became apparent that there was an immediate and intense need that was not being met in Platform Tennis. John knew a simple ball machine was not enough. He resolved to transform his ball machine into an extensive training experience that brought advanced technology, pro expertise and the player community together for all racquet sports. And that’s how Volley began!
