"Dear Oscar,
Your revolutionary teaching methods have help me in a way that even I am having hard time believing how well I’m playing. Last year I was a mediocre player, today, I have come to become someone to fear, a dangerous player if you will in my tennis league. Finally, after 22 years playing tennis, I got my very first trophy. I feel most proud of my accomplishments and my improvement…and as much as I like to thank me for working so hard, I like to dedicate my trophy to you and to my dear mother for getting me my first racquet 22 years ago." Carlos

"Oscar's techniques are incredible. Back in 1982 he was with me (coaching) in Germany and the students called him "the American who taught tennis in two hours". Over and over, he had total beginners rallying 40, 60 balls back and forth in just two hours of instruction. He also helped the Weiden Tennis Club have an undefeated junior tennis team that year and get our main team to the Bundesliga." Jurgen Fassbender, former #1 player in Germany and Top Ten player in the world.

"When my children were very young and just starting to play tennis, Oscar gave them drills that were fun to do. He generated an interest and eagerness for the game so that they wanted to play more, and as a result, they became motivated to play better. Oscar's relaxed style of teaching conveys a sense of comfort and confidence to his students so that they look forward to working with him and can enjoy the consistent improvements that result from his teachings." Vincent Spadea Sr, father of former #4 American and 19th ranked in the world.

"My team has won three NCAA titles and I have been named NCAA "Coach of the Year" twice. I say this only as a reference point. I was very fascinated with your work and have thought a lot about it since. I plan to use your methodology in my classes. In my pursuit of coaching excellence I was with you on many concepts and yet found many of the things you emphasized quite eye opening." Bob Hansen, Univ. of California Santa Cruz.

"I've been a teaching pro for about 13 years. During that time I've come across many theories (some great and some not so great). I would usually test them in a lesson. If they work, I keep using them. Well, I've been keeping a lot of theories and material from your book and using them daily with my lessons, with great results!" Scott Gilmore, Fort Walton Beach, Florida.
