AG candidate Maura Healey met with voters on Saturday in Pittsfield.

PITTSFIELD, Mass. — Maura Healey has already overseen half of the attorney general's office. Now, she wants to take it all over.

With Attorney General Martha Coakley now seeking election as governor, Healey has launched a campaign to replace her.

Currently overseeing the attorney general's public protection and business and labor bureaus, the Democrat says she knows the "power and possibilities" the office has to make positive impacts in people's lives.

"I know how important it is for Massachusetts to have an attorney general's office that is nation leading, that leads the nation in standing up for civil rights and giving a voice to those who are vulnerable," Healey told members of the Berkshire Brigades on Saturday at Dottie's Coffee Lounge.

"And in leading the nation in protecting consumers and leading the nation in thinking about smart approaches to criminal justice reform, public safety and drug addiction."

Healey grew up in Hampton Falls, N.H., and moved to Massachusetts to attend Harvard, where she received her undergraduate degree in government. She is the oldest of five siblings with her mother being a school nurse and father a high school teacher.

After graduating, she went overseas to play professional basketball. She returned to Massachusetts and received her law degree from Northeastern University.

Healey worked for a federal judge overseeing the cleanup of Boston Harbor before becoming a litigator at a private law firm.

"I jumped at the chance seven years ago to take a 70 percent pay cut and join the attorney general's office as chief of the civil rights division. And I saw, over the last several years, that there is no office where you can have a greater impact on people's lives," she said.

One of her largest accomplishments in the office was successfully fighting against the federal Defense of Marriage Act (DOMA), she said. At the time, the president and U.S. Department of Justice were defending the law.

"To me it was a matter of fairness," she said, adding a story about how a couple wanted to be buried together in a state veterans cemetery but were being blocked by the government.

She also took on predatory lenders, putting together a litigation team to go after banks participating in those practices. Healey was the first in the nation to bring a civil rights case against a lender and she also started the Home Court program, which used settlement funds to help residents modify their mortgages.

One of her first issues she tackled in the attorney's general office was writing the buffer zone law regarding access for women to abortion clinics. That law survived supreme court challenges. She has challenged laws that allow physicians to deny contraceptive care to patients.

And she says there is a lot more she can do if elected. Healey wants to "really tackle" the issue of drug abuse, which has become an epidemic across the state. She says there is a real shortage of beds for mental health and addiction treatment programs.

"Using settlement proceeds from the office — when we sue pharmaceutical companies and others — I want those resources to go to beefing up services for those kind of treatments and care," she said.

From the office, she says she will also "bring people together" to do a better job at prescription drug monitoring.

That stance earned her the endorsements of the mayors of Holyoke and Northampton and Hampshire County Sheriff Robert Garvey on Tuesday.

She also vowed to go after the growing for-profit schools market that "pocket" federal student loans but do not provide an education that gives students the tools for jobs.

"It is predatory and it is wrong," she said.

Healey also wants to advocate for a revamping of the state's criminal justice system. She says the state needs to provide more job training, life skills training and counseling to those in jail so that they don't come back. Meanwhile, on "the front end," there needs to be more options than jail. She wants courts to identify individuals who are in danger of continually going through the court system and provide drug treatment and other programs to stop the slide.

"I think you have a real opportunity to convene and lead that conversation," she said.

Entering the race in October, when she resigned from the attorney general's office, Healey says she wants "to be the people's point guard."

"I've been in that office. I've seen the power and the possibility of that office. In my mind it was a very easy decision because I am so passionate about this and so committed to building on the success of that office," she said, and boasts of being the only candidate who has worked in the office. "I think Massachusetts can lead on all of these issues."

She has gained support from state Rep. Tricia Farley-Bouvier, D-Pittsfield.

"When it comes to equal rights, when it comes to consumer protection, when it comes to making sure everybody in the commonwealth is treated fairly, the office of attorney general really leads that fight. So it is important to pay attention to all of the offices that are being fought for this year," Farley-Bouvier said. "I'm supporting Maura because she's done the job. She is a lawyer. She has run about 50 percent of the attorney general's office for about seven years."

Healey is vying for the Democratic nomination with former state Sen. Warren Tolman of Watertown, an attorney and former gubernatorial candidate, and champion of the clean elections law.

John Miller of Winchester, an attorney and expert on construction law and public infrastructure contracting, is the Republican candidate.
