Khuong and Huyen both played tennis recreationally, sharing their passion for the sport with their son from a young age. Khuong, a real estate lawyer based in Garden Grove, and Huyen, a former math teacher in Anaheim, have always prioritized family values. Their children’s names, Learner and Justice, reflect their principles. “An attorney seeks justice. A teacher seeks a learner. They were virtuous names,” Khuong explained in an interview with the LA Times.
Who is Learner Tien?
At just 1.5 years old, Learner picked up a racket, and by the age of five, he was already competing in tournaments. His first match took place at the Racquet Club of Irvine, close to their home. Although his early success was undeniable, Learner did not immediately pursue a professional tennis career. His parents supported him during a period when he stepped away from the sport.
His father Khuong, in fact, coached him until he was 12 years of age before he got into the USTA program. During his teen years that he met Eric Diaz, who became his first official coach and has been by his side ever since and Diaz comes from a tennis family himself, his father is the legendary University of Georgia men’s coach Manny Diaz which gives him a unique perspective on coaching young talent.
Under his father’s guidance, Learner practiced on community courts in Irvine until he was around 10 or 11 years old. His first victory came at just under six years old, when he won a tournament in Upland, earning a trophy decorated with a jack-o’-lantern—a moment his family still remembers fondly. In 2023, Learner won the USTA Boys’ 18 national title twice, reached two junior Grand Slam finals at the Australian Open and US Open, and claimed the 2023 Australian Open junior doubles title.
Despite only being 17, Tien played a semester of college tennis at the University of Southern California before turning professional and also began high school early, aged 11-and-a-half.
The lefty’s guilty pleasure is candy and favourite school subject is English and the American said his best quality is his composure and his worst quality is his indecisiveness.
Now ranked World No. 114, Tien has already achieved success on the ATP Challenger Tour, winning three titles before turning 19. His rapid progress earned him a spot at the 2024 Next Generation ATP Finals. As Learner won his second-round match against former World No. 1 Daniil Medvedev, his family continues to provide unwavering support.
