He rose to prominence playing Rafi on the FX comedy series The League and has since established himself as a versatile performer appearing in films, television series, and animated programs. Mantzoukas is also a prolific podcaster and screenwriter who continues to expand his creative footprint across multiple entertainment mediums.
A graduate of Middlebury College, Mantzoukas began his career as an improv comedian before training at the Upright Citizens Brigade Theater. He later became a co-host of the popular film discussion podcast How Did This Get Made? alongside Paul Scheer and June Diane Raphael. His fast-talking, high-energy performances have made him a sought-after guest actor in both comedy and dramatic projects throughout his career.
Early Life and Background
Jason Mantzoukas grew up in Nahant, Massachusetts as the oldest child of Cynthia and William Mantzoukas. Both of his parents are second-generation Greek-Americans, and he has described himself as “100 percent Greek.” He has one younger sister named Melissa. His upbringing in the Boston area provided him with opportunities to explore his creative interests from an early age.
Mantzoukas began taking drum lessons at age 10 and studied under Steve Barrett for more than eight years. He has cited Stewart Copeland, Stephen Perkins from Jane’s Addiction, and Jimmy Chamberlin from The Smashing Pumpkins as his biggest musical influences during his formative years. Beyond drumming, he participated in jazz and marching bands during high school and also played guitar in a cover band called Slygoul.
He attended Swampscott High School, graduating in 1991. During his high school years, he served as captain of the boys’ soccer and track teams and was president of the marching band. Mantzoukas then enrolled at Middlebury College in Vermont, where he majored in religion. He continued his jazz drumming at the college level, performing with a bebop group. After graduating in 1995, he received a prestigious Watson Fellowship that enabled him to travel for nearly two years through North Africa and the Middle East studying religious and transcendental music.
During his fellowship, he spent approximately seven and a half months living in Morocco, studying and recording Gnawa music. He also traveled to Egypt, Israel, Turkey, Jordan, and Syria. Notably, he was arrested once in Morocco for an expired tourist visa and was detained in Turkey to prevent him from traveling through an active war zone. Upon returning to the United States, he moved to New York City in 1998.
Path to Comedy
Mantzoukas first began writing comedy sketches during his junior and senior years of high school for variety shows. His formal introduction to improv came through the Otter Nonsense Players at Middlebury College, where he became fascinated with how improv required the same skill set as performing jazz. While performing with the Otters, he met and began practicing long-form improv with fellow performers Jessica St. Clair, Dan O’Brien, and Rodney Rothman.
After moving to New York City, he began performing regularly at the Upright Citizens Brigade Theater and was mentored by Amy Poehler. He joined the improv team Mother, one of UCB’s earliest house teams. During his time at UCB, Mantzoukas worked in the computer graphics department at J.P. Morgan for over three years while continuing his comedy career.
He formed the comedy duo The Mantzoukas Brothers with fellow comedian Ed Herbstman, and Time Out New York magazine named them the Best Improv Duo in 2006. He also collaborated extensively with Jessica St. Clair, appearing with her in the sketch show We Used to Go Out and the long-form improv show First Date. Together, they pitched a pilot to HBO that was not picked up but earned them a development deal with Comedy Central. Critics compared their work to the legendary comedy duo Nichols and May. Mantzoukas also taught advanced improv classes at the Upright Citizens Brigade Theater.
