Justin Francin

Franzen grew up in Lakewood, Colorado, and began performing comedy as a teenager at Fiore's Sports Bar in Highlands Ranch. He pursued formal improv training in Chicago, studying at Second City and iO (formerly ImprovOlympic), developing his performance and teaching practice under Chicago's primary long-form institutions before returning to Colorado.

Back in Denver, Franzen taught improv and performed at various venues in the city before founding Grafenberg Productions in 2013. Prior to securing a permanent home, the company performed at spaces including the Comedy Room, Atlas Theater, Backstage at Beryl's, and Deer Pile. Grafenberg launched The Playschool, a five-level improv curriculum, and grew a consistent student and performer community around its structured long-form approach.

In 2018 Grafenberg opened a dedicated venue at 1223 21st Street in Denver's Ballpark neighborhood, housed in space behind and below El Charrito restaurant. The company ran an Indiegogo crowdfunding campaign to fund the buildout, establishing a dedicated stage and classroom facility for the first time in the organization's history. The venue allowed Grafenberg to combine regular performance runs with ongoing Playschool classes under one roof.

Franzen has characterized Grafenberg's aesthetic as more theatrical and refined than conventional short-form improv, describing the company's work as blending narrative elements similar to Curb Your Enthusiasm and Saturday Night Live. He has taught improv in Denver and at festivals nationally, including in New York, Chicago, Cincinnati, Omaha, and other markets. Performers in Grafenberg include ensemble teams such as The Couch and For the Record. Francin's national improv festival teaching work, which has taken him to festivals in New York, Chicago, Cincinnati, Omaha, and other markets, reflects a broader footprint in the improv community than a strictly Denver-based career would suggest. His festival teaching has given him exposure to improv communities outside Denver and established him as a recognized teacher beyond his home market, contributing to Grafenberg Productions' reputation within the national improv scene as well as the local Denver context.

His ensemble team development within Grafenberg, including the Couch ensemble and For the Record ensemble that perform under the company's umbrella, reflects the institution-building approach that characterizes serious regional long-form companies: developing multiple performing groups within a single organizational structure rather than relying on a single ensemble to carry all of the company's programming. This organizational structure more closely resembles the house team model of major institutions than the single-ensemble model of many regional companies.

His training background at Second City and iO in Chicago before returning to Denver gave him grounding in the major institutional approaches to long-form improv pedagogy, which he has applied to the Denver context with awareness of both the resources and the limitations that a regional market provides compared to Chicago's concentrated training infrastructure. His public articulation of Denver improv's challenges, including the market's historical difficulty achieving mainstream cultural penetration, reflects a pedagogical self-awareness about the specific obstacles that regional improv institution-building faces.
