San Diego for their Summer Puppetry Convention. He attended San Mateo High School, joining prestigious alumni Alicia Silverstone and Barry Bostwick. He began performing professionally in the San Francisco Bay Area, most notably in several productions with American Musical Theatre of San Jose (including "On The Twentieth Century" with Jo Anne Worley) and earned his membership into Actors' Equity Association. He applied for and was accepted to the American Musical and Dramatic Academy in New York City, where he studied in their two-year program.
