Andrew Moskos

RolesCo-Founder

Andrew Moskos is a Chicago-born improv performer, director, and co-founder of Boom Chicago, the English-language improv comedy theatre he established in Amsterdam in 1993 with childhood friend and Northwestern classmate Pep Rosenfeld and fellow Northwestern graduate Ken Schaefle. Over thirty years, Boom Chicago became the most internationally prominent American-tradition improv theatre outside the United States, launching the careers of Seth Meyers, Jordan Peele, Jason Sudeikis, Brendan Hunt, Joe Kelly, Amber Ruffin, and Kay Cannon, among dozens of others who collectively contributed to approximately fifty television productions. Moskos co-authored 'Boom Chicago Presents the 30 Most Important Years in Dutch History' (Akashic Books, 2023), with forewords by Seth Meyers and Jordan Peele.

Career

In summer 1992, Moskos and Rosenfeld conceived the idea for an English-language improv comedy theatre in Amsterdam during a postgraduate European trip. The Amsterdam Board of Tourism rejected the concept in writing, stating that 'Dutch people do not want to see a show in English.' That rejection letter is now framed at Boom Chicago's office. Moskos, Rosenfeld, and Ken Schaefle, with Saskia Maas as their first employee, launched Boom Chicago's first shows in summer 1993 in a salsa bar's back room, drawing approximately fifty audience members per show.

The theatre grew through a series of venue expansions: from the salsa bar to Iboya on Korte Leidsedwarsstraat (85 seats) in 1993, to Studio 100 on Lijnbaansgracht (180 seats) in 1994, to the Leidseplein Theater (270 seats) in 1997, which Boom Chicago renovated with a kitchen, bar, and professional sound and lighting. In 2013 the theatre moved to the Rozentheater on the Rozengracht, a former 1913 cinema with three performance spaces totaling approximately five hundred seats. Boom Chicago performed on the Second City Mainstage in Chicago, a distinction Moskos has described as remarkable given their origins: they became the only visiting group ever to perform on that stage.

Moskos performed with Boom Chicago from 1993 through 2000 and subsequently served as Artistic Director. He directed numerous productions including 'Going Down: A Comedy Show about Pessimism,' the 2004 election show 'Mr. America Contest,' 'Kick This: A World Cup Comedy with Balls' (2006), 'Bango!' for the 25th anniversary (2018), and subsequent productions on AI, US politics, and 1990s sitcom culture. The 25th anniversary in 2018 featured sold-out performances at the Royal Theatre Carré, a 3,000-seat venue, with Seth Meyers. The 30th anniversary in 2023 comprised a twelve-day comedy festival with thirty shows.

With Rosenfeld and Maas, Moskos co-founded Boom Chicago for Business, the corporate communication and humor training arm of the organization. In 2004 he led the creation of Boom Chicago Video, which produces comedy content for broadcast, streaming, and mobile, including the Comedy Central Netherlands show and content for Microsoft, Heineken, and MTV. He co-founded InterActing, a nonprofit using improvisation to help teenagers with autism develop social confidence.

Moskos has coached Dutch Prime Minister Mark Rutte on speeches and written content for the Dutch Correspondents Dinner. He hosts and writes for major international conferences including Brand Minds, DPW Amsterdam, OnBrand, and KPMG events, and coaches C-suite executives on presentations. He attended the 2011 White House Correspondents' Association Dinner as a guest of Seth Meyers.

In 2023, Moskos co-authored 'Boom Chicago Presents the 30 Most Important Years in Dutch History' (Akashic Books) with Rosenfeld, Maas, and journalist Matt Diehl. The book received forewords from Seth Meyers and Jordan Peele and was reviewed by Publishers Weekly, Vulture, and the Chicago Tribune.

Historical Context

Boom Chicago's founding in 1993 placed American-tradition long-form improv comedy in Amsterdam at a moment when the form's institutional infrastructure barely existed outside Chicago and a few American cities. The theatre's sustained development over thirty years, from a fifty-seat back room to a multi-venue 500-seat complex, documents how the Chicago improv model could be transplanted into a non-American cultural context and thrive there at an institutional scale that few American regional improv theatres have matched.

The character of the alumni list, which includes not only major American comedy television figures but also Dutch television personality Arjen Lubach and the Ted Lasso team of Sudeikis, Hunt, and Kelly, reflects Boom Chicago's dual position as a staging ground for American performers developing international material and as a cultural bridge between American comedy and Dutch entertainment. Amber Ruffin's emergence there as, ultimately, the first Black woman writer on network late-night television in the United States represents one of Boom Chicago's most historically specific contributions.

The theatre's performed engagement with Dutch and European politics, including the Rutte speech work and the production of shows on American elections for Dutch audiences, demonstrates how an improv-tradition organization can situate itself as a civic and cultural commentator in its adopted country rather than as a foreign novelty.

Teaching Philosophy

Moskos's pedagogy and leadership practice emphasize the transferability of improv principles to professional and civic contexts beyond comedy performance. The Boom Chicago for Business arm, which he co-founded, applies yes-and thinking, active listening, and ensemble communication principles to corporate training for major European organizations. The InterActing nonprofit extends the ensemble principles of improv into social development work with teenagers on the autism spectrum. His executive coaching practice applies the same observational and improvisational skills he developed as a performer to the preparation of C-suite speeches and high-stakes presentations.

Legacy

Boom Chicago is Moskos's primary legacy, and it is one of the most significant institutional contributions to the international spread of American-tradition improv comedy in the history of the form. The theatre launched the careers of performers who have collectively reshaped American comedy television across SNL, Jordan Peele's films, Ted Lasso, Pitch Perfect, and a dozen other major productions. Its sustained thirty-plus-year operation in Amsterdam, through multiple venue expansions, a pandemic, and a sequence of institutional elaborations into corporate training and nonprofit programming, makes it a model for what international improv institution-building can achieve.

The 2023 book, with forewords from two of the most prominent alumni of the theatre, constitutes a primary document of Boom Chicago's institutional history and places that history within a broader narrative of Dutch cultural life over thirty years. For the archive, Moskos represents the generation of Chicago-trained improvisers who carried the form internationally and built institutions outside the United States that have had disproportionate influence on American comedy through the performers they trained and launched.

Early Life and Training

Moskos was born in Chicago and grew up in Evanston, Illinois. His father, Charles C. Moskos, was a distinguished military sociologist and longtime Northwestern University professor described by the Wall Street Journal as the nation's most influential military sociologist.

He and Pep Rosenfeld, who would become his co-founder, met as children in Evanston and both attended Northwestern. After graduating, Moskos trained at iO Chicago and worked as Director of Education Projects at Chicago United, a private nonprofit advocacy organization, from 1990 to 1993.

Personal Life

Moskos was born in Chicago and raised in Evanston, Illinois. He has been based in Amsterdam since the founding of Boom Chicago in 1993.
