Leominster Mayor Dean Mazzarella reached a milestone at Monday night’s inauguration ceremony. Once Lt. Gov. Karyn Polito swore him (plus city councilors and School Committee members) into office, Mazzarella wrapped up his 25th year leading the city.

“Twenty-five years of an open door policy,” he said in his State of the City address. “Twenty-five years of calling people back the same day. I’m proud of my years as a public servant. Thanks to planning, strong leadership and the support of all of you, Leominster is in the best position it’s ever been to embrace the future. I can’t wait to get started.”
