Her mother, Juanita, was a community volunteer and educator who taught English and typing and also mentored students of color in San Mateo.

[4] Her father, Nathaniel, was a civil rights activist and, like his wife, was also an educator, teaching for nearly 20 years in Richmond, California, before becoming the first Black school principal in San Francisco in 1968,[5][6] which helped to inspire Renel to achieve her goals.

It was at Mills where Brooks-Moon co-founded a gospel choir called "The Black Women's Collective", a group she credits for pulling her out of her shell and putting herself in front of a microphone.

At first, she was simply reading scripts and produced material but soon began booking and talking with her own guests due to the connections she had made while growing up and living within the community.

Brooks-Moon was approached by then-program director "The Duke" Dave Schollen who connected her with KFRC's on-air crews in order to create a demo tape.

A week after the demo tapes were sent off, Brooks-Moon was given her own Top 40 music show which aired at midnight on the weekend, which introduced listeners to "Rockin' Renel".

While Renel had already been promoted to the 10 PM hour after a new program director came to the station, she got a chance at the morning show when DJ Sue Hall went on maternity leave.

Thus, KISQ (dubbed "KMEL's big sister" by the execs in charge) would end up doing the same: playing songs from the late 1980s along with current Top 40 hits.

[9] Over the years, Renel has lent her voice to numerous historic moments in Giants' history, including the team's three World Series victories in 2010, 2012, and 2014, an experience she described as "Beyond thrilling", "nerve-wracking", "stressful" but also "exciting" and "the most fun".

[11] On March 18, 2024, the Giants announced that they were "mutually and amicably" parting ways with Brooks-Moon, citing difficulties in negotiations regarding a contract extension.

[13] In a press statement, Giants President and CEO Larry Baer said, "Renel has been the familiar and inspirational voice for generations of players and fans at Oracle Park.

[14][15][2] Ann Killion of the San Francisco Chronicle noted that Brooks-Moon was the team's "most visible non-playing Black employee" and that the ownership had dubbed her "expendable", adding that the move was "bizarre" and a "terrible move for a team whose majority owner Charles B. Johnson funds right-wing politicians who were supportive of undermining a democratic election and who have tried to disenfranchise Black voters across America."

Killion also reported that friends of Brooks-Moon had said that she had been pushed out by management due to her public objections to Johnson's political leanings and for her outspoken support of Black Lives Matter.

"[17] Longtime sports TV and radio personality Rod Brooks criticized the timing of the announcement and separation, adding that it was "Either a massive coincidence, or it was done that way on purpose."

[2] Oakland native, social activist and longtime Bishop O'Dowd High School boys basketball coach, Lou Richie, stated that it "would have been nice if they had figured it out, considering that she's such a rarity", adding, "It's like losing Barry Bonds or Mark McGwire, right?

"[2] Assemblymember Matt Haney (D-San Francisco), posting to his Twitter account, called Killion's op/ed piece "spot on" and added that the decision to part with Brooks-Moon was "absolutely unacceptable from the Giants.

"[14] The Giants used several different PA announcers for the 2024 season[18] until the end of July when they settled on her permanent replacement, Carolyn McArdle, the former voice of the Triple-A Sacramento River Cats.

[20] Matt Haney, the District Supervisor who bestowed Brooks-Moon with the honor proclaimed that she "wasn't just another announcer" and that she "was, and is, an icon in the Bay Area."

Brooks-Moon noted that she hoped that her career as a PA announcer would help in "opening up possibilities for young girls" and has actively tried to encourage them to do what she has been doing, adding, "That's absolutely the most rewarding part of this job.
