From 1985 to 1990, Tonio served as one of my coaches and improved my clay-court game. His knowledge and understanding of how to approach clay-court tennis proved invaluable. With Tonio's help, I won my first Grand Slam title in 1987 at Roland Garros and earned the World No. 1 ranking. After the French Open win, Tonio and I traveled to tournaments in Hamburg, Berlin, Paris, and New York. We have remained friends and continue to train together before my charitable exhibition matches.

I met Tonio in 2013, and since then, we have stayed in close contact. His passion for continuously improving as a coach is one of his greatest strengths. That passion has given him an exceptional understanding of the technical, physical, and mental aspects of the game. His experience on tour as a former professional player, combined with his dedication to developing his coaching skills, makes him one of the best coaches in the world. I have learned a great deal from him by sharing experiences, methodologies, and perspectives on life. Tonio is truly a top coach for players of all levels.

I have known Tonio since I was 11 years old. He is an absolute pleasure to work with. After only a few sessions, I was already able to see a dramatic improvement in my game. He is able to identify what you're doing wrong and give you tips on how to fix it. He's a positive person who provides encouraging and constructive feedback. He takes the extra time to talk you through things and continues to work on specific areas whenever needed. Overall, he is a highly recommended coach!

I met Tonio at the age of 17, when we were both starting on the professional tour, and I have had the privilege of witnessing his journey ever since. He was a conscientious player, and he brought that same dedication to his development as a tennis coach. He has invested countless hours understanding every aspect of the game, particularly the role of the individual within it. Tonio will share the very best of his knowledge and experience. It is an opportunity well worth taking.

I had the chance to spend three seasons with Tonio during the German Tennis League. One of his greatest strengths was his ability to understand my game and believe in my potential, helping me perform at the highest level of my ability. His empathy and understanding made him an invaluable coach to have by my side.

I started working with Tonio in August 2020, and we instantly developed a strong connection. We share many similarities in our personalities. First and foremost, Tonio is an exceptional person. He genuinely wants the best for me and has shared so much knowledge and wisdom throughout our journey together. He has taught me how to approach the game and how to play in a way that suits my style. He is the only coach who has ever told me that my defense and fighting spirit are actually strengths—qualities I should never lose. He has also taught me a great deal about positioning and how to move forward to the net effectively. Thanks to Tonio's guidance, I recently became the No. 1 NCAA singles player in the country. I'm excited to continue our journey together and reach new heights on the professional tour.
