Through Chicago Fire's many seasons, we've watched the firefighters at Firehouse 51 show up for one another through life's toughest moments, proving that their bond goes far beyond simply being coworkers. And that same sense of family extends beyond the screen.
The Chicago Fire cast is an incredibly tight-knit group that is always showing up for their co-stars, whether that be coming out to support their new ventures or simply hyping them up on social media. Just like the fictional characters they play, the Chicago Fire cast are more than coworkers; they’re family, and family always shows up for one another.
The latest example of this comes from Chicago Fire star Miranda Rae Mayo, who is rallying support for one of her co-stars as they face a difficult battle with cancer.
On Friday, November 13, Mayo took to Instagram to share a message of support for longtime cast member Robyn Coffin, hoping to use her platform to rally followers to support Coffin in a time of need.
“This beautiful and wonderful woman is in need of some support. You may know her as Cindy Herrmann on our show. Any and everything helps,” Mayo wrote via her Instagram Stories, which was accompanied by a screenshot of the recently launched GoFundMe campaign.
As Mayo highlighted, Coffin plays Cindy Herrmann on Chicago Fire, the wife of David Eigenberg’s character Christopher Herrmann. Cindy was first introduced in the show’s second episode, making her one of the show’s longest-tenured recurring characters, with Coffin having appeared in over 60 episodes and made an appearance in every season. We have not yet seen Cindy in season 15, and we now know that Coffin’s battle with breast cancer is the reason for her absence.
Longtime fans will remember that Cindy has also faced her own cancer scare on Chicago Fire. During season 11, Cindy was diagnosed with lung cancer, setting up an emotional storyline for the Herrmann family. Thankfully, Cindy ultimately made a full recovery, but the storyline is one that takes on an especially emotional significance given what Coffin is now facing in real life.
Much like how the Firehouse 51 family rallied around Cindy, Coffin's co-stars are doing the same with Mayo helping to bring awareness to Coffin's diagnosis as she faces a challenging journey ahead. With surgery and radiation ahead, the GoFundMe shared by Mayo aims to help support Coffin and her family as she takes time away from work to focus on her health and her cancer battle.
“As of now, on December 3, 2026, Robyn will undergo a right partial mastectomy with magseed localization. Radiation will follow. Robyn has a pre-op visit on November 24, 2026. If that visit results in affirming the right partial mastectomy, Robyn is expecting to be out of work for three weeks,” the GoFundMe explains. “If a full mastectomy is required, Robyn’s time off work will increase quite a bit, as the surgery is much more extensive. When Robyn doesn’t work, she doesn’t get paid. So, this GoFundMe is not only to fill in the gaps that insurance will surely leave but also to help sustain Robyn and Grant while Robyn is off work.”
The Chicago Fire cast has already begun showing up for Coffin in a big way, with Mayo and Hanako Greensmith among the fundraiser's top donors, according to the GoFundMe page. Now, fans have an opportunity to join them in showing their support and helping Coffin and her family as they navigate this difficult chapter.
