Philosophy

Our education goals

First and foremost, we would like to thank the many players and parents who have experienced the highs and lows of this sport together with us. We are proud not only of our successful players, but also of those who have learned to change their goals over the years and adapt them to reality. "Success cannot be coached."

At the end of the day, we just want our players to be happy. That's why we have the utmost respect for all those players who have decided to end their tennis careers, either on their own initiative or on our advice. Even though this is fortunately only the minority, these "dropouts" are still a big part of our experience. TennisGate is committed to making a significant contribution to preventing these dropouts.

ENJOY THE GAME

All of us at TennisGate are coaches (mostly with children of their own) who know from experience that there is one factor critical to success: every player must enjoy the game. This may sound trite or obvious, but it's a weekly topic for everyone who works in player development.

Oliver Heuft

EMBRACE THE LEARNING PROCESS

Tennis is a very complex and demanding sport where failure and frustration are always present. The only way to be successful in the long run is to learn and also embrace the learning process. Whether player, coach or parent.

Jürgen Müller

CHILDREN NEED TO BECOME MORE MOBILE

It is frightening to see the functional condition in which some children come to tennis training. But it is even more alarming that parents are completely surprised by this and assess it completely differently. Of course, children who play sports are usually well above average. But their functional weaknesses still urgently need to be remedied if one wants to favour the future and their development.

Silvester Neidhardt

SET MODERATE GOALS

Education and knowledge are the crucial companions to setting goals in moderation. Unrealistic expectations, along with injuries and coaching mistakes, are largely responsible for players ending their careers prematurely and turning their backs on tennis.

Edgar Giffenig

INVOLVE ALL TARGET GROUPS

If you want to be successful as a club and move safely into the future, then it is important as a club manager to have all the needs of the members in mind - and also to "educate" everyone. Not only the players, but also the parents and ultimately even the whole environment.

Eva Birkle-Belbl

FUN IS THE #1 FACTOR

First of all, it doesn't matter if you are coaching competitive players or introducing beginners to the sport. As a coach, you have to have fun. Enjoyment of tennis and development is the decisive factor, not only for recreational tennis, but also for competitive tennis.

Tom Gullikson
ATP Tour Player, USA Davis Cup Captain, USA Olympic Coach, USA Director of Coaching

In my capacity as a National Coach and later the Davis Cup Captain, I was fortunate to work very closely with Edgar in his capacity as a USTA Coach from 1990 to 1995. Edgar has a great understanding of the game of tennis and was very good at communicating with the player’s. His high level of energy and enthusiasm that he brought to the teaching court everyday had a very positive effect on the player’s and his fellow coaches as well. Edgar also is a tremendous student of the game, and never stops learning interacting with his fellow coaches in his quest to become the best coach he can be.
