Mayor Martin J. Walsh held a press conference after touring Boston Medical Center on Wednesday.

Mayor Martin J. Walsh made three more appointments Thursday, including Michael Dennehy, who will serve as interim commissioner of public works. Dennehy, who was the department’s assistant superintendent, will succeed Joanne Massaro, who had been commissioner since 2010.

The mayor also named Jim Gillooly, deputy commissioner of the Boston Transportation Department, to serve as the interim commissioner of that agency.

He tapped Justin Holmes, the director of constituent engagement, as interim chief information officer.


All three will assume their new positions immediately, according to an e-mail sent by Walsh’s new chief of staff, Dan Koh.

The e-mail said more appointments are coming soon.

“We’re at an incredible moment in Boston’s history -- the energy is exciting and tangible,’’ Koh wrote. “We look forward to working with each and every one of you to move Boston forward -- together.”

The announcement came Thursday evening, several hours after the mayor publicly welcomed William B. Evans as the new police commissioner, and Superintendent William Gross as superintendent in chief of the force.

Walsh said he picked Evans, a 33-year veteran of the department, because he shares the mayor’s belief that city leaders, elected officials, and the community must work together to attack root causes of violence.


Gross, a 28-year veteran of the force, is the first African-American to serve as superintendent in chief.

On Tuesday, Walsh also named six people to key positions in his administration.

He picked Joyce Linehan, a close campaign adviser, as chief of policy; Joseph Rull, another senior campaign adviser, as chief of operations; and state Representative Eugene L. O’Flaherty, a Walsh ally, as corporation counsel.

Walsh also appointed Trinh T. Nguyen, chief of staff at the Boston Housing Authority, as interim director of the Office of Jobs and Community Service. Keith Williams, who was associate director of neighborhood services, became interim director of Office of Small and Local Business Enterprise.

Alejandra St. Guillen, head of the Latino nonprofit Oiste, was selected as interim director of the Mayor’s Office of New Bostonians.


Over the weekend, Walsh picked former city councilor Felix G. Arroyo as his chief of health and human relations.
