Network television viewers might be acquainted with Rob Gleeson as a charming second-banana in various national commercials. Aficionados of the Los Angeles improv-comedy scene know him as a charming leading-man in various stand-up and storytelling shows. Raised in suburban Milwaukee, Wisconsin, minutes from the Konik childhood homestead, Gleeson’s energy and visage are Midwestern unthreatening, which serves him well when shilling for corporations. But his astonishing improvisational chops are what’s got us excited. A recent epic appearance on “The Todd Glass Show” podcast with fellow comic Ian Karmel demonstrated that Gleeson has the ears and wit to create humor out of virtually nothing. You’ve seen him, whether you meant to or not. Now, listen and smile.
