Susan Messing is an American improviser, actor, writer, and teacher from Short Hills, New Jersey, who has been a central figure in Chicago improvisation for nearly four decades. She has the distinction of having been hired directly to The Second City Mainstage, is a founding member of The Annoyance Theater, created iO Theater's Level 2 curriculum, and currently teaches at the University of Chicago. Named Improviser of the Year by the Chicago Improv Festival and Funniest Woman in Chicago by Chicago Magazine, she is regarded as one of the city's finest performers.
Messing grew up in Short Hills, New Jersey, and graduated from Northwestern University with a theater degree in 1986. After graduation, she began performing improvisation at iO Theater, where she appeared on the Harold team Blue Velveeta.
She was hired directly to The Second City Mainstage, a rare distinction that bypassed the typical path through the Touring Company. At Second City, she wrote and performed in two Mainstage revues and directed the National Touring Company.
In 1989, Messing became a founding member of The Annoyance Theater, where she created roles in over thirty original productions. Her credits at The Annoyance include Co-Ed Prison Sluts (the longest-running musical in Chicago history), That Darn Anti-Christ, The Real Live Brady Bunch, and the Judy Blume adaptation What Every Girl Should Know. Her critically acclaimed show Messing With A Friend, in which she improvised a full show with a different guest each week, ran for over ten years at The Annoyance.
As a teacher, Messing created and taught curriculum at iO Theater and iO West, The Annoyance Theatre, and The Second City. She designed iO's Level 2 curriculum. She has been an adjunct instructor at Loyola University, DePaul University, and The School at Steppenwolf, and currently teaches improvisation at the University of Chicago.
Her television and performance credits include the HBO/US Comedy Festival in Aspen, Comedy Central's Premium Blend, and NBC's Late Fridays. Her stand-up act with her puppet, Jolly, became a signature piece that showcased her range beyond improvisation. She has appeared in film, including a role in Let's Go To Prison.
As a writer, her essays have been published in The Second City Almanac of Improvisation and in Charna Halpern's Art By Committee. She presented "Braving the Unknown" at TEDxUofC in 2014. She married former Saturday Night Live and Sesame Street writer Michael Clayton McCarthy in 2012.
Messing continues to tour the United States and internationally, performing and teaching workshops that bring her distinctive approach to improvisers at every level of experience. Her teaching engagements span from local theater companies to international improv festivals, and she has developed a reputation as one of the most transformative workshop leaders in the global improv community.
Historical Context
Messing's career spans the three institutions that have defined Chicago improvisation: iO Theater, The Second City, and The Annoyance Theater. Her founding role at The Annoyance places her in the generation of performers who built Chicago's alternative comedy scene in the late 1980s, alongside Mick Napier and the ensemble that created a theater defined by its irreverence and willingness to push boundaries.
Her work at iO under Charna Halpern and at Second City gave her a comprehensive understanding of both long-form improvisation and sketch comedy development. The curriculum she designed for iO's Level 2 program has shaped the training of thousands of improvisers who passed through the theater's educational pipeline during its most influential period.
Messing With A Friend, her decade-long solo show at The Annoyance, demonstrated the depth of trust and skill that sustained improvisational practice can produce: a single performer creating a complete show with a different partner each week, relying entirely on the moment. The show's longevity testified to Messing's ability to create compelling, unpredictable performance regardless of who shared the stage with her.
Her ability to move between the structured ensemble format of Second City revues, the anarchic creativity of The Annoyance, and the Harold-based long-form work at iO gave her a versatility that few Chicago performers have matched. This cross-institutional experience informed her teaching, allowing her to draw on the strengths of each tradition.
Teaching Philosophy
Messing's teaching is known for its directness and energy, emphasizing commitment, personal risk, and the principle that if performers are not having fun, they are the only ones not having fun in the scene. Her approach demands that students bring their full selves to the stage and take responsibility for their own enjoyment and engagement, treating improvisation as a practice of generosity and presence rather than technique alone.
Legacy
Messing's significance to Chicago improvisation lies in her sustained presence across all three of the city's major improv institutions and her influence as one of the most sought-after teachers in the art form. Her awards, including Improviser of the Year from the Chicago Improv Festival, Best Improviser from the Chicago Reader, and Funniest Woman in Chicago from Chicago Magazine, reflect recognition from critics, audiences, and the improv community itself.
Her teaching at the University of Chicago brings improvisation into the academic environment of one of the world's most prestigious research universities, demonstrating the form's intellectual legitimacy and connecting the Chicago improv tradition to the university that helped give rise to it through the Compass Players in the 1950s. Her curriculum design for iO shaped the training of a generation of performers, and her continued international teaching and performance career ensures that her influence extends well beyond Chicago.
Her TEDxUofC talk "Braving the Unknown" articulated the principles that drive her teaching: that improvisation is a practice of courage, generosity, and presence that applies far beyond the stage. Her essays in The Second City Almanac of Improvisation and Art By Committee have contributed to the published literature of the form, providing practitioner perspectives that complement the theoretical and historical texts.
