Vanessa Lo, 18, the senior class president, had the honor of announcing Garcia as the prom queen Saturday night.
But for Lo, it was no surprise.
"I already expected it because of the amount of applause and support during his speech," said Lo, whose went to the prom with Perez, the newly crowned prom king.
Lo said that besides two of the girls who lost the title to Garcia Saturday night, who she said were "not too happy" with the situation, the majority of the class was happy with the results.
"We're accepting change, our school is open-minded, we support everyone despite the differences," said Lo. "It's equal opportunity for everyone."
One of Lo and Garcia's peers, Juan Espinoza, 17, told the Los Angeles Times that he wasn't as happy as most of his friends about the crowning.
"I'm not really happy about that," Espinoza told the paper. "He should've run for prom king."
Garcia and his peers graduate in the wake of several big stars: Notable alumni of the high school include the members of the rock band the Red Hot Chili Peppers and actress Mila Kunis. Actress Demi Moore also attended the school until she dropped out at age 16.
Zubiate, the principal, said that it's not surprising for anyone who has been to the school that so many talented adults graduate from the institution.
"The kids here really do their own thing," said Zubiate. "We're lucky that here, unlike many schools in the L.A. area, we don't have to worry about racial tensions."
Lo echoed this, saying that "everyone hangs out together" and that her peers genuinely like each other.
Students at the school expressed a range of reactions following Garcia's crowning. But Zubiate said that most of the response has been positive and that he has received calls from all over the world asking to talk to their newest prom queen.
"Garcia is very well-adjusted and that's tough for any kid at this age," said Zubiate. "Even though he's a senior it's still a tough time. They're about to wander out to the real world, and what comes with that if you're gay or not gay is hard."
"It seems like he's ready," said Zubiate.
