Classes

Improv classes for everyone: a six-week Foundations program for first-timers, then Characters, Narrative and Advanced Skills. New cohorts start every other month at the Shelton Theater. No experience needed, just a willingness to play.

Corporate Training

Playshops (because it's not work) for teams of any size, built around your group's experience and goals: creativity, communication, confidence. At the theater, at your office, or wherever your team gathers.

“This isn't a show you sit back and watch, it's an experience you're part of. Grab your drinks early, because once it starts you won't want to leave, and bring a group. Highly recommend!”
