Marty Walsh to be sworn in as new Mayor of Boston

CHESTNUT HILL, Mass. (WHDH) — Marty Walsh will be sworn in as Boston’s 48th Mayor on Monday morning. The ceremony will take place inside Conte Forum at Boston College, Walsh’s alma mater.

 On Sunday, Walsh talked with a group of senior citizens at a Northeastern brunch, a warm up for his big inaugural speech.

"I'm getting a little nervous for the speech. I practiced it a little bit last night and we made some edits. I'm going to practice again tonight, make a few more edits. So I'm a little nervous about that,” said Walsh.

Boston's new mayor is already filling positions, including one of his former rivals in the campaign, Felix Arroyo, who will be the new head of Health and Human Services in the city.

"I actually approached him on it and he said he would be very interested. We had conversations and I'm honored to have Felix Arroyo. His heart, his passion, is about poverty, about closing that gap," Walsh said.

Also this weekend, Walsh filled two openings on the school committee and named his chief-of-staff. He plans a number of announcements in the coming days.

"I think part of it is showing where the city is going a little bit, part of it is bringing in some new ideas,” he said.

Walsh's arrival means the official departure of Mayor Tom Menino, who held the office for decades. As Walsh prepares to move into city hall, he says his team will also be ready for the next big storm, whenever it comes.

"If there is snow Monday night, we're ready for it,” Walsh said.

A formal gala will be held Monday night at the Hynes Convention Center.
