Biography


Early life
Yeun was born in Seoul, South Korea, to South Korean parents Je and Jun Yeun. His father was an architect in South Korea before moving his family to Regina, Saskatchewan, and later to Michigan. Yeun was raised in Troy, Michigan in a Christian household. Yeun’s parents began calling him “Steven” after meeting a doctor by that name. His parents owned beauty-supply stores in Detroit.

Yeun received a bachelor’s degree in psychology with a concentration in neuroscience from Kalamazoo College in 2005. At Kalamazoo, he met Jordan Klepper through Klepper’s sister and later followed him to Chicago to join Second City.

Career
Yeun’s interest in acting and improv came during his freshman year at Kalamazoo, when he watched the college’s improv group, Monkapult. He auditioned for Monkapult, but was initially rejected before successfully joining the group during his sophomore year. Yeun revealed to his parents that he planned to pursue an improv career in Chicago instead of enrolling in law school or medical school. His parents, while unhappy with the decision, were supportive, according to Yeun, and gave him two years to pursue acting.

Yeun moved to Chicago in 2005, living in the city’s Lincoln Square with his brother. Shortly after graduation, he joined Stir Friday Night, a sketch comedy group composed of Asian-American members. Other alumni of the group include Danny Pudi from Community. He joined The Second City in Chicago before moving to Los Angeles in October 2009.

Yeun’s biggest role to date was Glenn Rhee on The Walking Dead, an AMC television horror drama based on the comic book series of the same name. The series began in 2010 with Glenn as one of the original main characters who fights to survive in a violent apocalyptic world infested with flesh-eating walkers as well as other humans, some of whom are more dangerous than the walkers. The drama is the highest rated series in cable television history, with its third through sixth season garnering the most 18 to 49-year-old viewers of any cable or broadcast television series. The series has received mostly positive reviews from professional television critics. Yeun left the show in 2016 after his character Glenn was killed off in the season 7 premiere.
