I have been luckily enough to play alongside and to practice with both Gero and Karsten during my time in solingen. They create a training environment that is fun, motivating and successful. The information and knowledge that karsten has obtained through his years as a coach is beneficial for players of all levels both on and off the court. The experiences that Gero has had playing at such a high level of tennis helped me both playing alongside him on the doubles court and helped me make improvements on the practice court.
