"Dear Nico,

After working together for several years, I would like to share my impression of our collaboration with you: You have greatly helped our team at the Tennis Association Mittelrhein in the area of mental strength. It is worth mentioning that you have not only supported our players consistently but also assisted and improved the coaches.

With your energy and dedication, you always strive to bring out the best in all athletes. You have provided us with skills that allow us to deliver our best performances even in high-pressure situations. Topics such as concentration, attitude, motivation, handling anger, to name just a few, have significantly improved all athletes.

Dear Nico, we thank you very much for your motivation, meticulousness, dedication, endurance, and professionalism, and we hope to continue our positive collaboration."
