Vincent Campbell
Intermediate Technical Theatre Class;

I joined Tri-School in 2009 as freshman attending Servite High School and immediately became hooked on the arts. I participated as a technician all four years of high school, spending countless hours after school working in the theatre. Tri-School became my home away from home. After graduating from Servite in 2013 I enrolled at California State University Fullerton pursuing a Bachelors of Science in Computer Science, but I never really left Tri-School. I remained heavily involved in helping with the productions. In 2014 I was invited back to teach the Tech 1 class, I accepted, and have been happily teaching it since. Additionally I have worked with local production and performance rental companies and have worked an assortment of productions at the Anaheim Center for the Performing Arts. I am always excited to come back to my Alma Mater to spark student's interest in the arts just like my mentors sparked that interest in me.
