Jack Dempsey, a Boston firefighter for 35 years, was appointed commissioner of the city’s fire service last Friday. Dempsey has served in the interim role since the retirement of former Commissioner Joe Finn last month.

Mayor Walsh said Dempsey “has dedicated his life in his professional career and personal capacity to promoting safety and wellness for firefighters, and I look forward to his continued leadership in this critically important department."

Dempsey most recently served as Chief of Operations for the department, where he oversaw all division of the Boston Fire Department, including the engine company, fire prevention, ladder company, rescue company, safety and special operations, emergency planning and preparedness, training and personnel. Until his promotion to commissioner, he was the highest-ranking uniformed firefighter in the force.

"As a lifelong member of the department, this is a tremendous honor for me, and I look forward to building on the strong foundations set to ensure the safety and well-being of our firefighters and our community,” Dempsey said.
