As a player, the TennisGate Tennis and Ball School in Villingen was my home since I was a little boy until I left for college. There I developed the fundamentals that my college coach Marc Booras build upon to help me become the player I am today. I still use many of the videos on the site and even appear on some of the clips.

Edgar Giffenig, Jürgen Mueller and Oliver Heuft have developed many players in their long coaching careers. Among them Dominik Koepfer, who was the number 1 player in college tennis in 2016. Dominik trained at the TennisGate Academy from the age of 6 to 18 before joining Tulane. TennisGate observes and analyses top player and uses this information to design age-appropriate training systems for the next generation of players. Their vast on-court experience working at all levels of the game coupled with their long-time involvement in coaching education makes TennisGate the perfect partner for any coach.

TennisGate has been a fantastic resource to help me develop my current players, such as Dominik Koepfer, who's excellent foundation was built by these coaches. All of the tools on TennisGate, with their attention to detail and variety of options are perfect for assisting me in designing my collegiate practices.

For many years I played ice hockey and tennis in my youth. Although I did not become a tennis professional in the end, the coaches in the TennisGate tennis school provided me with important basics that were valuable for my career as a professional athlete.

Bob and I travelled the world with Edgar when we were juniors and he helped coach us to become the players we are today. The input and advice he gave us during these crucial years was invaluable. Edgar is not only a technical and strategic genius, but is incredibly hard working and dedicated to his profession. And most importantly, he is one hell of a guy and a great friend!

With Oliver Heuft and his agency TennisGate Media, we found the perfect partner for our DTB Online Campus project. TennisGate digitally implements our training and sports science content in an innovative and high quality way. In addition, Oliver has the necessary expertise in tennis instruction as a Coach with the highest DTB A-certificate.
