Patrick Hallahan has been a teacher and director since age sixteen. Working for the non-profit group Children's Theatre Network of California, Patrick worked on dozens of classic musicals (everything from "Music Man" and "My Fair Lady" to "West Side Story" and "Into the Woods") to put himself through college. After graduating from UCLA's School of Theatre, Film, and Television with a BA in theatre, Patrick was accepted to The Juilliard Drama Division, where he graduated in '00.

Patrick worked as an actor in New York for six years before moving to southern california to continue to teach, direct, and act closer to his family and friends. Since returning to California, he has worked for the Metropolitan Arts (MET2) group, Arts Northridge, AMDA in Hollywood, and the Southern California Musical Theatre, directing productions, running workshops and classes, and staging showcases for graduating conservatory students. He ultimately hopes to return to school within the next few years to get an MFA in Directing for the stage.

Patrick’s productions for Upstage include the summer camp shows "Oh Mamma Mia", "High School Musical 2" and "Into the Woods Jnr"; and the after-school productions of "You’re a Good Man, Charlie Brown" and "Singin’ in the Rain". Recently he completed a successful summer directing "Cats" and "Once On This Island Jnr".
