He was a house-team performer at New York's legendary comedy venue The Upright Citizens Brigade Theatre. He performed on Maude Night, UCB's monthly sketch comedy showcase, as well as in many improv, sketch, and character shows. He was a long-time student of the theatre's Advanced Study Improv Program, as well as the UCB Academy, and his experience with improv influences much of how he approaches performance.

He is a strong baritone singer, with some notes on either side. As a coach, he has instructed many diverse groups and individuals in acting, improv, and his specialty: accents and dialects.
