Brendan Sullivan started improvising almost 30 years ago in Chicago. He is an actor, corporate improv trainer and was a member of the legendary Harold team Blue Velveeta at iO-Chicago. We talk to him about how he found his role on that team, which was made up of strong personalities, how he learned to play things honestly, and the best way for older improvisers to play with the younger generation. In this moving interview, Brendan also talks candidly about the death of his 24-year-old son, Charlie, last year, and the dangers today of drugs that are laced with fentanyl.
