Our Instructors
Daren Auld

I was born in Brooklyn, New York and raised in Haiti where I was introduced to the game by my father. After moving to Southern California at the age of 10, my love and passion for tennis truly began to develop while playing on the junior circuit (USTA Southern California ranking, #1-14's and #5- 18s). After competing through high school I then went on to play on the professional circuit for eight years playing all over the world as well as competing on the European Bundesliga international team. 

After my playing career was over I transitioned into coaching at the developmental and professional tour level. That was where I fell in love with the sport all over again. I learned to appreciate tennis in a different way. I became passionate in communicating with my students in ways that would not only get the best out of themselves but to also help them enjoy the process and the journey as much as the result. That process has had the added benefit of allowing me to form connections and lasting friendships with amazing people from all walks of life.

Brenn Auld

I was introduced to the game in Haiti by my father who himself was an instructor. After moving to California, I played through the Juniors and developed more and more of a passion for every aspect of the game. I played through high school, junior college and then all over the world playing wildcard, open, and futures pro events. During that time I was a hitting partner for various pros as well, after touring. I coached privately for years before starting my academy that I ran with my brother.

I have a deep passion for coaching and believe that I have an ability to contribute to helping players of varying abilities improve their skills and overall game. I focus on helping players build a better understanding of the game through clear communication, fun dynamic drills, and discipline. I'm proud to have built long-lasting relationships with many students over years of teaching them a sport that can last a lifetime.

Renard Johnson

Renard started playing tennis at the age of 11. As a nationally ranked player in the juniors he then went on to play collegiate tennis (scholarship) for Hampton University. He and his team won the NCAA division 2 title making Hampton the number one ranked collegiate team in the nation. After college I played around the world on the satellite and challengers professional circuit. After the world tour I went on to represent and play for one of Europe's strongest professional club teams in Germany for 10 years. Having retired from professional tennis I began a new chapter teaching others the sport I love.' I taught lessons in Germany and after several years moved back to the United States. I have been teaching tennis full time to all ages and skill level from beginners to nationally ranked players for over 30 years. I enjoy teaching all levels. I especially enjoy teaching beginners the fundamentals and a solid foundation they will have for the rest of their lives. Fluent in German.   

Yi Fang

I learned to play tennis at the age of 5 and started to train competitively a year later. I competed in multiple state tournaments in China. I earned the certificate of national second level athlete in tennis when I was 12. Tennis made up a huge part of my childhood life, I’ve devoted every weekday in the afternoon and almost the entire weekends to tennis all the way through junior high in China. I went to America to attend high school, and I was the #1 singles/doubles and the captain of our tennis team throughout my entire high school days. 

While attending the University of Iowa, I was provided a tennis instructor position and began to teach at the Hawkeye Tennis & Recreation complex. I taught both Private and group lessons and trained students from little kids to adults. Applying knowledge I acquired from Exercise Science degree, my focus was to design sports specific training programs that incorporate not only tennis practice drills, but also performance drills designed specifically for tennis such as speed/agility drills, footwork drills, and proper warm up/cool down routines, etc. I kept coaching for a while after college and went on pursuing a master’s degree in Exercise Science at Northeastern University.

Dial Jones

Coaching for me is about helping you reach your tennis goals. I believe in improving your performance as a tennis athlete first, with winning being the result of achieving your goals.

Our program challenges our students to strive for improvement in areas, rather than a “winning at all costs” philosophy. We also believe in working together with our students in a cooperative manner in which decisions are collaborative and the training structure is flexible.

You, the student, should feel that the lesson is uniquely tailored to you and taught by a trained professional who enjoys teaching and being on the court with you.
