Irish American Laura Kavanagh was sworn in as New York City's first female Fire Commissioner on Thursday, October 27. 

Kavanagh, who had been serving as acting FDNY Commissioner since February, has become the first woman to lead New York City's Fire Department in its 157-year history. 

Kavanagh was sworn in on Thursday during an emotional ceremony at Engine 33, Ladder 9, in NoHo, where New York's first-ever Fire Commissioner John J. Scannell had his office. 

Mayor of New York City Eric Adams led the swearing-in ceremony, while dozens of top officials in city government joined Kavanagh on the podium. 

Kavanagh has been serving as the city's acting Fire Commissioner since former Commissioner Daniel Nigro stepped down without appointing a successor. Kavanagh had been serving as Nigro's second-in-command since 2017.

In a statement, Mayor Adams said he was "proud" to appoint Kavanagh as New York's Fire Commissioner, describing her as a "proven and tested leader."

"No matter her role, Commissioner Kavanagh has always been a leader — from helping to lead the FDNY’s response to the Ebola outbreak in 2015 to steering the ship during the COVID-19 pandemic, to directing a firefighter recruitment program that resulted in the most diverse applicant pool in the department’s history," Adams said. 

"New Yorkers and New York City’s ‘Bravest’ deserve an exceptional leader and Commissioner Kavanagh has the vision, the skills, and the compassion to lead the FDNY into the future." 

Kavanagh said: “For nearly a decade, I have served, learned from and worked on behalf of the New York City Fire Department. I have seen the sacrifices our men and women make, the talent and training they possess, and the bravery they display saving lives and protecting our city.

"This is the greatest city in the world and the greatest fire department in the world. To serve both is the honor of a lifetime.

“I am excited and grateful for the opportunity to lead this great department, and I thank the more than 17,000 Firefighters, EMTs, Paramedics, Fire Marshals, Fire Inspectors, and civilian personnel for all they do 24/7 to keep our city safe.”

Back in March, Kavanagh marched with the FDNY's Emerald Society up Fifth Ave for the 2022 New York City St. Patrick's Day Parade.
