John Nguyen
Staff Professional
John caught the tennis “bug” relatively late compared to other players. He starting playing in the seventh grade at 12 years old and was so enamored with the sport that he didn’t miss a single day of practice for the next two years.
His hard work paid off as he was able to start playing Varsity singles on his high school team as a Freshman and played all four years.
He later walked on to his local junior college team for one year and then returned to coach is former high school team for two years.
One of his tennis highlights was participating in a clinic with former #1 in the world and 7 time Grand Slam winner Mats Wilander. John was not only able to play with a legend, but also learn many invaluable insights into the game of tennis from one of the game’s legends.
He is PTR certified and feels fortunate to be able to teach tennis, a game that has taught him autonomy, self-discipline, sportsmanship, and contentment in life.
