Leo Costello
Leo Costello’s winning improv recipe: a little deadpan, a lot witty, and just a dash of absurd. Leo has been improvising with MBI since 2025, with previous training at UW Oshkosh and Backlot Comedy House (Oshkosh). During the day, he’s a multimedia producer at a nonprofit; in his off time, he’s a film enthusiast, vintage lover, and a gifted photographer. He is also a wizard at platformer video games.
