The interconnected universe of One Chicago has become a staple of modern television, weaving a complex tapestry of heroism, tragedy, and redemption across its three flagship shows. While Chicago Fire serves as the gritty, high-stakes anchor of the franchise, its medical counterpart has provided some of the most memorable character departures in recent memory. For fans of Firehouse 51, the doctors and nurses of Gaffney Chicago Medical Center have always felt like extended family, appearing in high-octane crossovers and building deep personal relationships with the firefighters. As the years have passed, several key players have moved on to new horizons, leaving viewers to wonder where the original stars of Chicago Med have landed since hanging up their stethoscopes.
One of the most significant shifts for the series was the departure of Nick Gehlfuss, who played the talented and often impulsive Dr. Will Halstead. As the brother of Fire’s Jay Halstead, Will was a vital link between the two shows. Since his emotional exit in the Season 8 finale, Gehlfuss has taken a step back from the grueling schedule of a network procedural to focus on more diverse creative projects. He has expressed a desire to explore roles that challenge the doctor-next-door image he cultivated for nearly a decade. While he remains a beloved figure in the Chicago universe, his focus has shifted toward independent film and potential stage work, proving that his range extends far beyond the emergency room.

Moving Beyond the Emergency Room
Another cornerstone of the original cast was Yaya DaCosta, who portrayed the fiercely capable Nurse April Sexton. Her departure was a major blow to the show’s romantic and professional dynamics. Since leaving the Windy City, DaCosta has flourished in the lead role of the drama series Our Kind of People, where she demonstrated her ability to carry a show as a powerhouse protagonist. She has also returned to her roots in modeling and advocacy, using her platform to discuss representation in the arts. While she made a brief, heartwarming return to Med to wrap up her character’s arc with Ethan Choi, her career trajectory is now firmly pointed toward producing and lead dramatic roles in prestige television.
Torrey DeVitto, known as the compassionate Dr. Natalie Manning, also transitioned into a new chapter of her life after six seasons of heart-wrenching medical cases. DeVitto has become a staple of the holiday movie circuit, starring in multiple successful projects for Hallmark and Lifetime. Beyond the screen, she has dedicated much of her time to philanthropy and environmental activism. Her presence in the Chicago universe is still felt, but she has successfully redefined herself as a versatile actress who can jump between lighthearted romance and serious advocacy work with ease.
New Frontiers for Legacy Characters
The departure of Brian Tee, who played the disciplined Dr. Ethan Choi, marked the end of an era for the series. Tee didn’t just walk away from the show; he transitioned into the role of a director, returning to the Chicago Med set to helm episodes and share his veteran expertise with the new cast. On the acting front, he recently starred alongside Nicole Kidman in the high-profile Amazon series Expats, a role that allowed him to explore a much more restrained and cinematic style of performance. His evolution from a series regular to a respected director and international dramatic actor is a testament to the growth that the One Chicago franchise fosters in its talent.
Even the veterans like Colin Donnell, who played Dr. Connor Rhodes, have found vibrant lives after Med. Donnell returned to his first love—musical theater—appearing in several high-profile stage productions and starring in the international crime drama Irreverent. His ability to pivot from a brooding surgeon to a comedic lead in a remote Australian setting surprised many fans and solidified his reputation as one of the most talented alumni of the franchise.
The Lasting Impact of the Med Alumni
The reason these “where are they now” updates resonate so deeply with Chicago Fire fans is that the characters were never just names on a call sheet; they were part of a living, breathing city. When we see Jesse Lee Soffer or Nick Gehlfuss move on, it feels like a neighbor moving to a new town. The success these actors have found after leaving the show reflects the high caliber of talent that Dick Wolf and his team consistently cast. They aren’t just leaving a show; they are taking the discipline and work ethic of the Chicago set into the wider world of entertainment.
As Chicago Med continues to introduce new faces to the ER, the legacy of the original cast remains a benchmark for the series. Whether they are directing, starring in streaming epics, or gracing the Broadway stage, the stars who built Gaffney Chicago Medical Center continue to thrive. Their journeys remind us that while the siren of an ambulance or a fire truck might be a constant sound in the city, the people behind the uniforms are always evolving, growing, and reaching for new heights.
