Asked in 2003, in the wake of a Vanity Fair magazine article about increased anti-Semitism in France, whether he had been the brunt of anti-Semitism while he was in France for the French Open, he responded that he was uncertain. "They're so impolite and rude in general, you don't know if they think I'm Jewish or whether I'm just another American tourist".
He is a member of the Southern California Jewish Sports Hall of Fame in 2003. He was inducted into the MetroWest Jewish Sports Hall of Fame in New Jersey in 2006.
He said he was proud to be a Jewish role model. He added: "When I played, I got a lot of support from the Jewish community. People identify me as a Jewish athlete. It's a strong responsibility, and I appreciate that."

## Post-playing career

Gimelstob was a blogger for Sports Illustrated (under the name "Gimel Takes All"), and served as a regular commentator for Tennis Channel. In 2010, Gimelstob was suspended from his Tennis Channel commentating duties for comments he made about President Barack Obama. He also presented tennis features and interviews for the TV Guide channel.
Gimelstob was one of the three ATP board representatives elected by the ATP player council. On May 1, 2019, Gimelstob resigned from the ATP Player Council after a series of controversies (see below) and subsequent pressure from Stan Wawrinka and Andy Murray. He also resigned from his job at the Tennis Channel.
John Isner hired Gimelstob as his new coach at the end of the 2014 season and worked with him until April 2016.

## Controversies
### Sexist comments

On June 17, 2008, when Gimelstob was a guest on the Washington, D.C., morning radio show The Sports Junkies, he referred to French tennis player Tatiana Golovin as a "sexpot", Czech player Nicole Vaidišová as a "well developed young lady", and French player Alizé Cornet as a "little sexpot".
Also in 2008, Gimelstob told Out Magazine: "The locker room couldn't be a more homophobic place. We're not gay-bashing. There's just a lot of positive normal hetero talk about pretty girls and working out and drinking beer. That's why people want to be pro athletes!"

### Domestic abuse allegations

In 2016, Gilmelstob's wife Cary sought a restraining order against him, alleging that he "physically assaulted, harassed, verbally attacked, and stole" from her. Cary also accused Justin of a placing a "video recording device in my bedroom" which captured "me having sex with another man" and that Justin threatened to show the footage to the couple's son.

### Assault case

In November 2018, Gimelstob was charged with assault after being accused of repeatedly striking Randall Kaplan while the venture capitalist, his wife and their two-year-old daughter were trick-or-treating on Halloween in West Los Angeles. Gimelstob denied the accusations. Gilmelstob later changed his plea to "no contest" to a felony battery charge, and was sentenced to three years’ probation and 60 days of community labor. The wife of the victim attributed the miscarriage of her unborn child to the stress of witnessing the attack. In 2019, he resigned from the ATP board of directors.
