City Councilor Michael P. Ross announced Thursday that he will be a candidate for mayor of Boston.
In a statement, he pledged “to continue building a better Boston.’’
“This week, our Red Sox returned for their home opener, providing Bostonians with a surge of hope, optimism, and renewal. Every year on opening day, I think back to 13 years ago, during my earliest days as a city councilor, when a small group of us stood together against powerful forces to save Fenway Park. All of Boston won that fight and look at the neighborhood today.
“Today, in that same spirit of community activism and determination to continue building a better Boston, I am announcing that I will be getting into the race for mayor.
“I love this city. I believe in its people and our limitless potential. It’s why, when I formally kick off my campaign in May, you are all invited to hear me share a progressive vision for Boston that is built on the values and diversity of our neighborhoods, and rooted in my upbringing and work on the city council.’’
Ross, a 41-year-old attorney who lives in Mission Hill, has been a district councilor since 1999. He raised his profile in 2009 when he became the first Jewish president of the Boston City Council. His father, Stephan Ross, is a Holocaust survivor liberated from the Dachau concentration camp by US troops in 1945.
In his tenure on the City Council, Ross has spearheaded improvements in Boston Common, pushed to increase physical education in Boston public schools, and helped create dog parks in city neighborhoods. He was one of the most vocal opponents of a plan to move Fenway Park.
As City Council president, Ross took a public stand against an arbitration award for Boston firefighters in May 2010, threatening to vote against the contract unless the union makes “meaningful concessions.’’
“If they don’t, I believe we have no choice — on behalf of the residents of this city — but to reject the award,’’ Ross said at the time in a heated speech at City Hall, describing what he called palpable “public outrage’’ over the settlement. “Seventy-four million dollars. A 19 percent increase. Paying firefighters to come to work sober.’’
Ross ultimately helped broker a deal between firefighters and the city with City Councilor Felix G. Arroyo, a vocal proponent of the union. Arroyo declared his candidacy for mayor earlier this week.
Ross is the latest entrant in an expanding field of mayoral hopefuls that already included state Representative Martin J. Walsh; city councilors John R. Connolly, Rob Consalvo, and Arroyo; Suffolk District Attorney Daniel F. Conley; and Bill Walczak, a founder of the Codman Square Health Center in Dorchester.
Two others, Will Dorcena and Charles Clemons, have said they are running but have raised little money. Several others have said they are considering a campaign.
