Park began attending UCLA in winter quarter of 1993. As a student, he co-founded "Lapu, the Coyote that Cares," the largest and longest-running on-campus Asian American theater company, now known as the LCC Theatre Company, in 1995. He credits his experiences with LCC for sparking his desire to pursue acting professionally and would go on to collaborate with many of its alumni. Their first performance was of "Treehouse Bachelor Society," a full length play Park had written, and it was performed at the Northwest Auditorium. Park was also a student volunteer for UCLA's official charity, UCLA UniCamp, and went by the camp name "CareMoose."
