"Do you find yourself saying over and over to your students, "That was a great lesson"? I have heard you say that at least a hundred times! What does that tell you...that you recruited the best students in the OC? No, it is a reflection of not only your giftedness as an athlete, but it is also a reflection of what a talented tennis teacher you are! You are so appreciated by so many of us! I am lucky to be one of them!"

- Jeff Pinter, Aliso Viejo

- Andrea Quimby, Corona del Mar

"I'm sending you this e-mail to let you know that Jake made the [Trabuco Hills] High School Varsity Tennis Team.  I want to thank you for the training that you gave him.  I believe that without it, he may not have even made the JV team.  I think that you provided him a solid foundation to work with. As his coach, I wanted to share this 'good news' with you."
- Steve Portanova, Rancho Santa Margarita

You took a pretty unathletic 8 year-old kid, and turned him into a tennis player worthy of playing [Santa Margarita Catholic] high school tennis. However, you have also taught me valuable life lessons. You have taught me the importance of a work ethic and hard work, as well as the rewards of perseverance. Thank you for everything. And I will miss you next year."

- Suji & Deepa Somasundaram, Laguna Niguel
