Chicago Med Cast: Every Actor and Character at Gaffney Chicago Medical Center
If someone has been following along with One Chicago Wednesdays on NBC, chances are the Chicago Med cast is one of the biggest reasons they keep tuning in. From long-running originals to exciting new additions, the cast of Chicago Med has always been a big draw for fans of the medical drama genre. Whether someone is just discovering the show or has been watching since the chicago med season 1 cast first scrubbed in back in 2015, there is always something new to learn about the talented group of actors keeping Gaffney Chicago Medical Center running week after week.
What Is Chicago Med?
Chicago Med is an American medical drama that airs on NBC and sits at the heart of Dick Wolf’s beloved One Chicago franchise, alongside Chicago Fire and Chicago P.D. The show first premiered in November 2015 and has since grown into one of network television’s most dependable dramas, now heading into its eleventh season. The series is set inside the fictional Gaffney Chicago Medical Center, where a team of doctors, nurses, and administrators navigate high-stakes emergencies, personal drama, and ethical dilemmas — often all in the same shift.
Season 11 premiered on October 1, 2025, continuing the show’s tradition of kicking off One Chicago Wednesdays at 8/7c on NBC. For those who cannot watch live, new episodes stream on Peacock the following day, making it easy to keep up with the cast of chicago med 2025 no matter the schedule.
The Current Chicago Med Cast in Season 11
Season 11 welcomed back the core ensemble that carried the show through a strong tenth run, though not without some meaningful changes. Most notably, original cast member Marlyne Barrett stepped away from the series after a decade at Gaffney, leaving a significant gap in the Emergency Department. Despite that departure, the cast of chicago med 2025 remains one of the strongest on Wednesday nights, blending familiar faces with the newer additions who joined during Season 10.
S. Epatha Merkerson as Sharon Goodwin
S. Epatha Merkerson has been the backbone of Gaffney since day one, playing Sharon Goodwin, the Chief Administrator who keeps the hospital’s lights on — figuratively and often literally. Merkerson is one of the few remaining original cast members and re-signed ahead of Season 11 to continue her tenure. Before Chicago Med, she was best known for her iconic run on Law & Order, where she played Lt. Anita Van Buren for many years. In her personal life, Merkerson was previously married to Toussaint Louverture Jones from 1994 to 2006.
Oliver Platt as Dr. Daniel Charles
Oliver Platt plays Dr. Daniel Charles, the warm and quietly brilliant Head of Psychiatry at Gaffney. Like Merkerson, Platt is an original cast member who re-upped his deal to bring Dr. Charles back for Season 11. Outside of Chicago Med, Platt has had a long and varied career in both film and television, with memorable roles in projects like Flatliners, Funny People, and the comedy series Huff. His portrayal of Dr. Charles has become one of the most beloved in the entire chicago med tv show cast, largely because of the humanity and depth he brings to every scene.
Steven Weber as Dr. Dean Archer
Steven Weber plays Dr. Dean Archer, the no-nonsense Head of the Emergency Department at Gaffney. Archer’s backstory includes a career in the Navy, an experience that left him dealing with PTSD — something the show has explored with honesty and care across multiple seasons. Weber is widely recognized for his role in the long-running NBC sitcom Wings, and has also lent his voice to animated projects like All Dogs Go to Heaven. Off-screen, Weber has been candid about how much he appreciates the collaborative environment at Gaffney. In a 2024 interview, he described the on-set culture as deeply supportive, noting the genuine connections between cast and crew.
Jessy Schram as Dr. Hannah Asher
Jessy Schram brings Dr. Hannah Asher to life as a senior physician in Gaffney’s OB/GYN department. Hannah’s journey on the show has been one of the more emotionally layered arcs in the series, touching on personal struggles that have tested both her career and her resilience. Schram was a recognizable face before joining the chicago med cast season 10 lineup — audiences may know her from Once Upon a Time, where she played Cinderella, as well as from her appearances in Mad Men and the film Unstoppable. Her chemistry with the rest of the cast has made Hannah one of the more compelling characters to watch evolve.
Luke Mitchell as Dr. Mitch Ripley
Australian actor Luke Mitchell joined the show in Season 9 as Dr. Mitch Ripley and has continued into Season 11 as one of the series’ central doctors. Mitchell previously appeared in The CW’s The Tomorrow People, as well as Agents of S.H.I.E.L.D. and Blindspot. He has been enthusiastic about his time on the show, speaking publicly about how much he enjoys coming in to work every day at Gaffney. His character, Dr. Ripley, adds a layer of quiet competence to the ED that has resonated well with viewers.
Sarah Ramos as Dr. Caitlin Lenox
Sarah Ramos joined the chicago med cast season 10 as Dr. Caitlin Lenox, an ED Attending with a clear mission: get Gaffney’s Emergency Department running at peak performance. Her arrival was not without friction — Dr. Lenox initially clashed with Dr. Archer, creating some of Season 10’s more entertaining dynamics. Ramos is a familiar name to NBC audiences, having appeared on American Dreams and Parenthood earlier in her career, and more recently in The Bear and Winning Time: The Rise of the Lakers Dynasty. In her personal life, she has been married to director and writer Matt Spicer since 2020, best known for co-writing and directing the film Ingrid Goes West.
Darren Barnet as Dr. John Frost
Darren Barnet made his debut as Dr. John Frost alongside Ramos in Season 10, rounding out the chicago med season 10 cast’s new additions. Dr. Frost is a pediatric resident who brings a warm, approachable energy to his young patients — though the show has hinted that there is more beneath the surface, with the character described as harboring a secret. Barnet is best known internationally for his starring role in Netflix’s Never Have I Ever, and has also appeared in Road House and Anyone But You. His addition to the show brought in a wave of new viewers familiar with his work outside of the One Chicago universe.
Notable Chicago Med Cast Departures Over the Years
No conversation about the chicago med season 1 cast and how the show has evolved would be complete without acknowledging the many talented actors who have passed through Gaffney’s doors over the years. The chicago med cast 2024 season was particularly notable for the departure of Dominic Rains, who played fan-favorite Dr. Crockett Marcel for five seasons before leaving ahead of Season 10.
The chicago med cast 2023 era also saw significant turnover, and looking further back, the chicago med cast 2022 period included the exits of several familiar faces. Over the course of its run, the show has said goodbye to Nick Gehlfuss as Dr. Will Halstead, Brian Tee as Dr. Ethan Choi, Guy Lockard as Dr. Dylan Scott, Sarah Rafferty as Dr. Pamela Blake, Asjha Cooper as Vanessa Taylor, and Yaya DaCosta as April Sexton — to name just the most prominent departures.
More recently, the chicago med cast 2024 chapter closed with Marlyne Barrett’s exit. Barrett had played Maggie Lockwood, the tough but caring ED charge nurse, since the very beginning, making her departure after Season 10 one of the more emotionally significant moments in the show’s history.
Despite all of this turnover, Chicago Med has done something quite impressive: it has continued to grow its audience and maintain strong viewership ratings. The ability to refresh its roster while preserving the emotional core of the show is a credit to both the writers and the producers behind it. It is also worth noting that chicago fire pd med cast changes have been a recurring theme across the entire One Chicago franchise, and each show has found ways to adapt and keep fans engaged.
Many fans who have been watching since the cast of chicago med season 1 days will recognize just how much the show has transformed — and how much of that transformation has actually worked in its favor.
Recurring and Supporting Chicago Med Cast Members
Beyond the series regulars, the cast chicago med has built a strong bench of recurring and supporting players who add richness to the Gaffney world.
Henderson Wade plays Dr. Loren Johnson, a general surgeon who also serves as a medical helicopter pilot for Helocare. His character’s military background — likely the Air Force — makes him a critical asset when patients in rural areas need emergency airlift transport to the hospital. Wade has also appeared in NCIS and Extant, bringing solid dramatic experience to the role.
Conor Perkins returns as Dr. Zach Hudgins, a first-year emergency medicine resident who has worked alongside several of Gaffney’s senior physicians. Perkins brings a theater-trained sensibility to the part, having studied at NYU’s prestigious Tisch School of the Arts and trained with the Atlantic Acting School. He also hosts his own bi-weekly podcast called Poor Unfortunate Podcast.
Brennan Brown rounds out the recurring lineup as Dr. Sam Abrams, a familiar face at Gaffney who has appeared in the show since its early days. In real life, Brown has been married to actress Jenna Stern — known for Law & Order: SVU — since 1998, and the two have one child together.
Chicago Med Cast in Real Life — Relationships and Personal Lives
Fans of the show often find themselves curious about what the people behind the characters are up to off-screen, and the chicago med cast season 1 veterans alongside the newer additions offer plenty of interesting stories.
Sarah Ramos and her husband Matt Spicer have built a life together in the entertainment world, with Spicer working behind the camera while Ramos continues to take on compelling on-screen roles. Darren Barnet, who became a household name through Never Have I Ever, has brought a younger fan base to the show and continues to be one of its more recognizable stars beyond the One Chicago universe.
S. Epatha Merkerson, a television legend whose work on Law & Order made her one of the most recognizable faces on NBC for decades, has kept her personal life relatively private following her divorce from Toussaint Louverture Jones in 2006. Oliver Platt and Steven Weber have both maintained long, respected careers that stretch well beyond Chicago Med, and their continued commitment to the show speaks to how much they value the work being done at Gaffney each season.
Overall, the cast of chicago med 2025 comes across as a genuinely close-knit group. Multiple cast members have spoken about the warm, professional atmosphere on set — something that clearly translates into the chemistry viewers see on screen every week.
