Mark Piebenga, a native son of Grand Rapids, MI, has been living and working in Chicago since 2002. When not ridiculously happy to be improvising with TNT at the Annoyance, he can be seen in the two brother show Piebenga Plumbing at the Bughouse Theater every second Friday. He was a founding member of improv/sketch groups American Dream and the Outsiders, with whom he performed at the Chicago Improv Festival, Chicago Sketchfest, the Miami Improv Festival, the Toronto Improv Festival, and Delfest at UCB in New York. He studied acting at Kalamazoo College, the Second City Conservatory, and the iO Theater Training Center in Chicago, and is an alumni of the Second City Touring Company.
