If you’ve watched even one season of Chicago Med, you know the drill. You get attached to a character, you start shipping them with a cynical surgeon, and then—poof. They’re gone. It’s a revolving door. Honestly, being an actress on Chicago Med is a bit like being a character in a horror movie; you never quite know if your contract is going to survive the next season finale.
The One Chicago universe is famous for this. Dick Wolf’s "procedural first, personality second" philosophy means the show is the star, not the actors. It’s brutal. But it also creates this fascinating alumni network of incredibly talented women who have moved through the halls of Gaffney Chicago Medical Center.
Take Torrey DeVitto. She played Dr. Natalie Manning for six years. Six! She was the emotional heartbeat of the show, the one who always seemed to be in the middle of a high-stakes ethical dilemma or a messy breakup with Will Halstead. Then, in 2021, she just... left. She wanted to pursue other creative avenues and spend time on her farm. It felt sudden to fans, but in the world of network television, six years is basically a lifetime.
The Natalie Manning Void and the Torrey DeVitto Legacy
When DeVitto exited, it left a massive hole. You can’t just replace a lead actress on Chicago Med and expect the chemistry to stay the same. Natalie Manning was polarizing. Some fans loved her "rules-be-damned" approach to patient care, while others found her self-righteous. But that’s what made her good TV. She wasn’t boring.
After leaving, DeVitto didn't just disappear. She leaned heavily into her advocacy work and took on projects like the Hallmark film The Holiday Stocking. It’s a classic move for One Chicago leads. They go from the grueling 22-episode-a-year grind to projects that allow for a bit more breathing room.
Then there’s Yaya DaCosta. As April Sexton, she was the glue. Nurses are the backbone of any real hospital, and April was the backbone of the show. Her departure was arguably the hardest for the "Chexton" shippers to swallow. She left to lead her own show, Our Kind of People, on Fox. It was a big swing. Even though that show didn't last forever, she actually came back for a guest arc to give her character a proper send-off. That’s rare. Usually, characters just disappear into a cab or take a job in Seattle.

Why Do They All Leave?
It’s the question that haunts Reddit threads every May. Is it the pay? Is it the Chicago winters? It’s probably a bit of everything. Working on a network procedural is a marathon. You’re shooting 14-hour days in the freezing cold. For a female lead, the pressure is immense.
- Contract Cycles: Most initial contracts for network TV land around the six-year mark. That’s exactly when we saw the big exodus of the original cast.
- Creative Stagnation: How many times can your character almost get fired or almost get married before it feels repetitive?
- The "Wolf" Factor: Dick Wolf shows are known for being well-oiled machines. If an actor wants more money or more creative input, the machine often just finds a new part.
Take Marlyne Barrett, who plays Maggie Lockwood. She’s been a staple since the beginning. Her journey has been incredibly personal, especially after she went public with her real-life uterine and ovarian cancer diagnosis in 2022. The show worked her illness into her filming schedule, showing a level of loyalty that isn't always present in Hollywood. She’s the survivor of the group, both on and off-screen.
The New Guard: Jessy Schram and the Evolution of Gaffney
Enter Jessy Schram as Dr. Hannah Wood. Her character arc is arguably the best-written one in the show's history. She started as a recurring character with a serious drug addiction, disappeared, and then came back as a series regular in recovery.
It’s a gritty role. Schram brings a vulnerability that feels different from the polished perfection of earlier seasons. She’s not just another actress on Chicago Med; she’s playing a character that represents a very real, very messy part of the medical profession. The writers have given her space to be flawed.
And we have to talk about S. Epatha Merkerson. She is the GOAT. As Sharon Goodwin, she has been the steady hand since day one. Coming off her legendary run on Law & Order, she’s the ultimate Dick Wolf veteran. She doesn't have the "will they, won't they" drama, but she provides the gravitas that keeps the show grounded when the younger doctors are making questionable life choices in the breakroom.

The Practical Realities of Being a One Chicago Lead
If you're an actress looking to join this franchise, you need to know what you're getting into. It’s not just about the acting. It’s about the branding. The "One Chicago" fan base is intense. They will follow you to your next project, but they will also roast your character on Twitter if you make a mistake in the ER.
Rachel DiPillo (Sarah Reese) is a prime example of how the show handles exits. Her character’s departure was abrupt—linked to the psychological fallout of her father’s actions. One day she was a rising star on the show, the next she was gone. Fans still ask if she’s ever coming back. As of now? Silence.
The turnover creates a weird dynamic where the "lead" role is constantly shifting. When Kristen Hager joined as Dr. Stevie Hammer in Season 7, people thought she was the new Natalie. She lasted less than a full season. Why? Creative reasons, apparently. It just didn't click. That’s the risk. You can be a phenomenal actress on Chicago Med, but if the chemistry with the existing ensemble isn't instant, the writers move on fast.
Where to Find Them Now
If you miss your favorites, here is the current status of the most prominent Gaffney alums:
- Torrey DeVitto: High-profile Hallmark lead and environmental activist. She’s very active on Instagram, showing off her farm life.
- Yaya DaCosta: Continues to land lead roles in prestige dramas and returns for the occasional cameo.
- Rachel DiPillo: Has largely stayed out of the public eye since her exit, which is rare in the age of social media.
- Mekia Cox: While she was only on Med for a bit as Robin Charles, she’s found huge success on The Rookie.
Navigating the Career of a TV Doctor
So, what’s the takeaway here? If you’re a fan, don’t get too comfortable. The show is built to outlast its cast. If you’re an aspiring actress, getting cast on a Wolf Entertainment show is like winning the lottery—it’s a steady paycheck, massive exposure, and a "family" for life, provided you can handle the pace.

The "One Chicago" girls' club is a real thing. You often see them supporting each other's charities or popping up in each other's comments. It's a grueling job that creates a specific kind of bond. They are the ones who know what it's like to fake a chest tube insertion at 4:00 AM in a studio that’s been cooled to 50 degrees to prevent the equipment from overheating.
The show's ability to keep going despite losing its biggest stars is a testament to the formula. But let’s be real: we still miss the original crew. There was a specific magic in those early seasons that’s hard to replicate with a constant stream of new faces.
Your Chicago Med Watchlist
If you want to track the evolution of these performances, pay attention to these specific turning points:
- Season 1, Episode 1: Watch the introduction of April and Natalie. See how they were positioned as the "heart" versus the "soul."
- Season 3, Episode 20: The peak of Sarah Reese’s psychological arc. It’s some of the best acting in the series.
- Season 6 Finale: The mass exodus. It’s a masterclass in how a show resets its entire dynamic in 42 minutes.
- Season 9: Watch how the show balances Marlyne Barrett's real-life strength with Maggie’s fictional struggles.
The show isn't just about medicine. It’s a case study in career longevity in Hollywood. For every actress on Chicago Med who leaves, a new one gets her big break. It’s the circle of life, Dick Wolf style.
Next Steps for Fans and Aspiring Talent
If you're following the careers of these women, the best way to support them is to look beyond the "Med" bubble. Follow their production companies—many, like Yaya DaCosta, are moving into producing. If you're an actor, study the "One Chicago" style. It’s a specific type of naturalism mixed with high-stakes urgency. It requires a lot of technical precision—you have to look like you know what you’re doing with that scalpel while delivering three pages of emotional dialogue.
Check out the official Wolf Entertainment social channels for behind-the-scenes footage of the current cast. They often post "day in the life" snippets that show the actual physical toll of filming in Chicago. It’s not all glamour; it’s a lot of parkas and coffee. Keeping up with the casting news on sites like Deadline or The Hollywood Reporter is also key, as they usually announce departures months before they air, giving you time to prepare for the inevitable heartbreak of another favorite character leaving the ER.
