Beth Lindstrom, whose resume includes top posts under former Gov. Mitt Romney and former US Sen. Scott Brown, is launching her US Senate campaign on Monday.
Lindstrom joins a field of GOP candidates hoping to take on Elizabeth Warren, the Cambridge Democrat who is up for re-election in 2018.
In an online video posted Monday, Lindstrom called herself an "independent-minded Republican who believes we can get things done if people would just get to work instead of trading insults or thinking about the next step on the political ladder."
A Groton resident, she worked as director of the Massachusetts Office of Consumer Affairs and Business Regulation while Romney served as governor. She was also Scott Brown's US Senate campaign manager in the 2010 special election.
"Some days I look at what's happening in Washington and I just shake my head," she says in the video. "The politicians like to think the problem is all on the other side but the truth is there's plenty of blame to go around. We can do better and you deserve better."
A "more formal" campaign announcement will follow in the fall, "but I want you to know I'm all in," she adds.
Other declared GOP candidates include state Rep. Geoff Diehl of Whitman and Shiva Ayyadurai, who claims he invented email, and Winchester businessman John Kingston.
