Once a month, Grafenberg owner Justin Franzen will perform a 50 minute improv set with a very special guest based on audience suggestion.
Justin has been improvising for 19 years. From humble beginnings in highschool speech and debate in Denver, to studying at iO Chicago and Annoyance Theater, Justin has spent his adult life absorbing improv theory and learning production. He has been a part of groups and shows such as Go-Go Manifesto, Improvised Tarrantino, and Ginger's Improv Ale House. Justin moved back to Denver to found his own production company and began teaching and coaching Chicago-style improv in 2013.
