“Rainer has been a wonderful coach for our daughter Barbara for several years. She has continuously improved her skills while developing a genuine love for the sport, thanks to his professional, supportive approach and strong focus on confidence and a healthy mindset.”

“I've been training with Rainer since I was eight. He encouraged me to see tennis as more than a leisure activity. I noticed weekly progress in my game and tactical understanding. He taught me that tennis is both physical and mental and helps in many ways beyond sport. Tennis became a meaningful part of my life and a source of mental and athletic growth.”

“Rainer guided our son from beginner to confident player with individualized coaching and great patience. His expertise covers technique and the mental side—handling pressure and competition—which we value hugely. He's an outstanding coach for players of all levels.”

“In over two years with Rainer I've learned more than in the eight years before and never had so much fun. He motivates me constantly and conveys the joy of getting better. He shows real understanding when school and training need to be balanced. I'm very grateful to have such a coach.”

“My daughter has been in Player Journey for three years. She's developed more self-confidence and fighting spirit—in tennis, school and life. She's learning that setbacks are necessary to progress. Despite competition pressure, her enthusiasm has stayed. The system supports players and helps parents accompany their children. As Churchill said: success is walking from failure to failure with no loss of enthusiasm.”

“Our daughter joined Player Journey at 12. In four years her tennis improved fundamentally and she developed physically, mentally and as a young woman. Thanks to Rainer's support as coach and mental coach, she integrated tennis lessons into daily life. Player Journey was both a top tennis school and a school of life. We recommend it without reservation.”

“Over six years Rainer coached our daughter into a skilled, passionate player. His holistic approach carried into every part of her life: she's more independent, confident and takes ownership of her development. We value the mentorship most—she trusts him and he brings out her desire to reach a high standard. We're grateful for his coaching and positive energy!”

“I didn't know tennis training could be so much more than hitting balls. Since 2018 with Player Journey I've improved technique, then tactics and match play, then mental strength. The change in mindset—in me and other athletes—is remarkable. Compared to other coaches, this is very personalized.”

“I started at 12 and didn't enjoy it much at first; Rainer helped me learn to love the game. Tennis is now a big part of my life and challenges me to grow. Through his support I've developed as a player and a person—more disciplined, confident and resilient. Competing at R4 level, I aim to keep improving and hopefully play on a university team.”
