Changes are on the horizon for the beloved NBC series ‘Chicago Fire’ as the show prepares for its 15th season, with significant departures from both the cast and behind-the-scenes leadership. Notably, showrunner Andrea Newman has stepped down after a fruitful 14-year tenure, handing over the reins to co-executive producer Victor Teran. Concurrently, longtime cast members Joe Miñoso and Dermot Mulroney have confirmed their exits, with their characters’ storylines expected to conclude in the early episodes of the new season.

Newman announced her departure in April 2026, setting the stage for a new chapter in the series. “Working at Chicago Fire, with the absolute best cast and crew in the business, has been the highlight of my career,” she stated as she reflected on her time with the show. Having started as a co-executive producer in 2012, she later became executive producer in season six and co-showrunner for two years before moving into her current role entirely.
Miñoso, who has portrayed firefighter Joe Cruz since the series premiered, is also set to leave in season 15. The actor is scheduled to make appearances early in the season to provide closure for his beloved character. Miñoso joined ‘Chicago Fire’ as a guest star during the pilot episode, quickly making the leap to a series regular by the beginning of season two. Reflecting on his time on the show, Miñoso expressed that landing the role fulfilled a childhood dream, stating, “I was so excited about the potential. I don’t think we could ever imagine that this is where we would’ve gone.”
Dermot Mulroney, who joined the cast as Battalion Chief Dom Pascal, confirmed his departure while attending a panel at the Flashback Weekend Chicago Horror Convention. He revealed that his run on the show would conclude with one final episode, expressing gratitude for the opportunities he had during his time on the series. “I loved every minute of it,” Mulroney said, highlighting the meaningful and challenging scenes he was part of throughout his two-season stint.
As these changes unfold, Newman noted the importance of cast turnover to keep the long-running series fresh and engaging. “In terms of storytelling and real life, 12 years is a long time, and things need to change,” she remarked in an interview last June. “You want new characters and you want new dynamics.” Her insights point to the evolving nature of television dramas, where sustaining audience interest often necessitates a shift in cast and creative leadership.
With a dedicated fanbase, the news of these departures has undoubtedly stirred emotional responses, as viewers prepare to bid farewell to familiar faces. The impact of Miñoso’s and Mulroney’s characters has been significant over the years, and their absence will surely be felt at Firehouse 51.
‘Chicago Fire’ has been a linchpin of NBC’s programming since its debut, attracting a loyal viewership and spawning a franchise that includes spin-offs ‘Chicago P.D.’ and ‘Chicago Med.’ The show’s ability to innovate while maintaining its core appeal has contributed to its longevity in an era when many series come and go quickly.
As the series prepares to welcome Victor Teran at the helm and navigate through these changes, fans can expect that Season 15 will bring forth new narratives and character dynamics, while honouring the legacy of those who have departed. The premiere, set for October 7 at 9 p.m. ET/PT, promises to deliver fresh content while addressing the emotional farewells to Miñoso and Mulroney’s characters.
With a blend of anticipation and nostalgia, audiences are set to embrace the next chapter of ‘Chicago Fire’, hoping to see new storylines that resonate as strongly as those that have come before.
