Since 9 1 1 first premiered in 2018, Kenneth Choi has become one of the show’s most beloved stars. Through his portrayal of firefighter and paramedic Howard “Chimney” Han, he has delivered countless unforgettable moments that blend humor, courage, vulnerability, and heart. Over the years, Chimney has grown from a witty first responder into one of the emotional anchors of Station 118, making him a fan favorite whose journey continues to resonate with audiences around the world.
Kenneth Choi was born on October 20, 1971, in Chicago, Illinois, to Korean American parents who had immigrated to the United States in search of better opportunities. Raised in a traditional household, his parents initially hoped he would pursue a stable career in business. In fact, Choi attended Purdue University to study accounting before realizing that his true passion was acting. Choosing to follow that dream was a difficult decision, especially because it went against his family’s expectations, but it ultimately changed the course of his life.
Like many successful actors, Choi’s career was built through years of persistence rather than overnight success. During the 1990s and early 2000s, he appeared in numerous television series, gradually earning recognition for his versatility. Audiences may remember him from The West Wing, House, CSI, Without a Trace, and many other popular dramas before he landed larger roles in both television and film.
His film career has been equally impressive. Choi appeared in The Wolf of Wall Street, Captain America The First Avenger, Spider Man Homecoming, Captain America Brave New World, The People vs Larry Flynt, and several other major productions. One interesting milestone in his career is that he portrayed two completely different characters within the Marvel Cinematic Universe, something only a small number of actors have done.
Before joining 9 1 1, Kenneth Choi was already familiar with producer Ryan Murphy’s work. He portrayed Judge Robert Chon in The People v. O. J. Simpson American Crime Story, delivering a performance that received widespread praise and further established him as one of television’s most dependable character actors.
Everything changed in 2018 when Choi was cast as Howard “Chimney” Han in 9 1 1. From the very first season, Chimney quickly stood out because of his unique personality. He could lighten the mood with humor during the most stressful emergencies while never losing focus on saving lives. That balance of compassion and resilience helped make him one of the show’s defining characters.
Throughout the series, Chimney has experienced some of the most emotional storylines. He survived a life threatening injury early in the show’s run after being attacked with a piece of rebar, endured personal heartbreak, struggled with questions about his future, and continually placed himself in danger to protect complete strangers. Despite everything he has faced, he has remained one of the most optimistic members of Station 118.
Perhaps the biggest turning point in Chimney’s life came through his relationship with Maddie Buckley. What began as an unexpected romance gradually developed into one of the strongest relationships in the series. Together they welcomed their daughter Jee Yun, overcame significant personal challenges, and eventually married in one of the most anticipated moments for longtime fans. Their relationship has become one of the emotional foundations of 9 1 1, with viewers celebrating every milestone along the way.
Another reason fans connect so strongly with Chimney is his friendship with Evan “Buck” Buckley and the rest of Station 118. Whether mentoring younger firefighters, standing beside Bobby Nash during difficult decisions, or sharing lighthearted moments around the firehouse, Chimney has consistently demonstrated loyalty, kindness, and an unwavering commitment to his team.
Away from the cameras, Kenneth Choi has maintained a relatively private personal life. Unlike many Hollywood stars, he rarely places his relationships in the public spotlight, choosing instead to let his work speak for itself. He has often spoken about the importance of representation in television and how meaningful it is to portray a multidimensional Asian American character whose story extends far beyond stereotypes.
Throughout the years, Choi has expressed gratitude for the loyal fan base that has supported 9 1 1. He has praised both the cast and crew for creating an environment built on friendship and mutual respect, something many viewers believe is reflected in the chemistry shared by the Station 118 family.
As 9 1 1 has continued to evolve, so has Chimney. From rookie paramedic to one of the station’s most experienced leaders, he has grown professionally while never losing the warmth and humor that made audiences fall in love with the character from the beginning. Many fans now view him as one of the natural leaders within Station 118 and someone younger firefighters instinctively look to for guidance.
With Bobby Nash’s heartbreaking death leaving an enormous void within the firehouse, many viewers have begun discussing who should help lead Station 118 into its next chapter. While nothing has been confirmed by the writers or ABC, Chimney’s experience, calm decision making, and ability to unite the team have made him one of the characters fans believe could take on even greater leadership responsibilities in the future. Whether that happens or not, his influence within the station has never been stronger.
More than seven seasons after his introduction, Kenneth Choi continues to deliver one of television’s most genuine and heartfelt performances. Howard “Chimney” Han is not simply a firefighter or paramedic. He is a devoted husband, a loving father, a trusted friend, and a courageous first responder who never hesitates to put others before himself. That combination of humor, humanity, and resilience is why Chimney remains one of the most beloved characters in 9 1 1, and why Kenneth Choi continues to earn the admiration of fans with every new season.
