Justin Gimelstob is a name that remains familiar to those who followed American tennis during the late 1990s and early 2000s. Born on January 26, 1977, in Livingston, New Jersey, Gimelstob quickly rose through the ranks of junior tennis to become one of the sport’s most recognized American doubles specialists. As of 2025, the 48-year-old former professional tennis player has an estimated net worth of $8 million, built from his tennis career, coaching roles, and media work.
Early Talent and Rise Through the Ranks
Justin Gimelstob showed early promise in tennis. By the age of 12, he was already ranked the top player in his age group nationally. This trend continued throughout his teenage years, as he also claimed the No. 1 spot at ages 14, 16, and 18. His dominance in the junior circuit pointed to a future professional career, and in 1996, at age 19, he officially turned pro.
Professional Career Highlights
Gimelstob’s professional career was marked by consistent performance, particularly in doubles and mixed doubles formats. While he did compete in singles, and won 10 singles titles in smaller tournaments, it was his doubles success that brought him international recognition.
In 1999, he reached a career-high ATP singles ranking of World No. 63. That same year marked a high point in his singles performance, but doubles remained his strongest area. By 2000, he had climbed to a doubles ranking of World No. 18, a testament to his adaptability and strategic play on court.
His most notable career achievements came in mixed doubles. Partnering with tennis legend Venus Williams, Gimelstob won two Grand Slam titles: the 1998 Australian Open and the 1998 French Open. Their chemistry and court synergy gave them a competitive edge, marking him as a Grand Slam champion in the process.
Throughout his career, Gimelstob earned just over $2.5 million in prize money. While this might not place him among the sport’s highest earners, it reflects a solid career by professional standards—especially in an era when endorsements and media work weren’t as widespread as they are today.
