Senate President Stanley C. Rosenberg often speaks about the importance of making the work of his chamber known to the public.

He should have plenty of help with that now.

Rosenberg announced the addition of a fifth person to his communications staff on Tuesday, giving him a public relations team that is more than double the size of previous legislative leaders — and the same size as Governor Charlie Baker's executive press operation.

Mara Dolan, a former Democratic state Senate candidate, party official, and radio host, will become the office's communications director, starting immediately with an annual salary of $100,000.

According to the news release from Rosenberg's communications staff, Dolan joins a press secretary, a deputy press secretary, a district communications director, and a new media manager.


The employees constitute a third of Rosenberg's staff of 15 full-time equivalent employees.

Rosenberg aides said most of the people on the communications team are not primarily focused on communications, but rather other areas, such as developing policy.

By contrast, House Speaker Robert A. DeLeo has two press staffers, a communications director, and a deputy communications/operations director, whose focus includes other areas besides media strategy and answering questions from reporters.

Rosenberg was elected president by his colleagues in January 2015. His predecessor in the leadership post, Therese Murray, had two press staffers, a communications director, and a deputy communications director.

Robert E. Travaglini, who was Senate president from 2003 to 2007, had one spokeswoman, with other staffers helping as needed on policy details.

Dolan, a lawyer, referred a request for comment to Rosenberg chief of staff Natasha Perez, who has an extensive background in communications, though she is not on the five-person communications team.

Perez said most of the staffers listed as being part of the communications team "are not primarily [focused on] communications."


She noted that the Senate president's office takes an "interdisciplinary" approach, with staffers involved in several areas, such as policy and media.

For example, she said communications is less than half of Matthew Bonaccorsi's and Andrew Basler's jobs, whose titles are, respectively, deputy press secretary and new media manager, according to the press release sent out by Pete Wilson, the press secretary.

Asked why people have titles that reflect media responsibilities if they do mostly nonmedia work, Perez replied with a prepared statement.

She said her team has a diverse set of skills and "frankly everyone on team Rosenberg participates in the overall communications strategy. In addition to serving as a resource for the 40 members of the Senate and their staff, the president's office is focused on increasing civic engagement with the general public, and promoting the legislative priorities of the Senate as a whole."

Perez added that the office believes strongly that "the only way to turn the tide on the current cynicism around politics is to use a multimedia approach to communicate clearly the work and effort involved in creating legislation that improves people's lives."

She declined to provide her office's communications payroll, salaries that — like those of other state employees — are footed by taxpayers.

But Rosenberg's four press staffers earned about a combined $225,000 in 2015, according to the state's Open Checkbook online database, which allows the public to look up state salaries.

With Dolan making $100,000, that would put Rosenberg's communications team payroll at about $325,000.


DeLeo's two press staffers earned a combined total of about $180,000 in 2015, according to the speaker's office. The House has 160 members, four times the amount in the Senate.

Baker's five press staffers in his executive office earned a combined total of about $365,000 in 2015, according to the state's Open Checkbook.

There are other press staffers in both branches of the Legislature, representing individual lawmakers and committees, as well as many in the state bureaucracy Baker oversees.

Rosenberg's communications strategy is notably different than the current speaker and governor.

While the two other Beacon Hill leaders are more likely to make declarative, decisive statements of what they believe, Rosenberg is more likely to float ideas as part of a broader policy development process.

The Amherst Democrat has governed with a philosophy of what he calls "shared leadership," bringing in his 39 colleagues to get their take, and leading by the will of the body, rather than by foisting his ideas upon them by fiat, as some of his predecessors did.

Several senators have said they like Rosenberg's style. But it tends to garner fewer headlines than DeLeo and Baker.

To be sure, Rosenberg has had need for a crisis communications team directly prior to and during his tenure.

Rosenberg's fiancé, Bryon Hefner, has raised eyebrows on Beacon Hill: The Boston Globe reported in late 2014, as Rosenberg prepared to ascend to the presidency, that Hefner's activities included talking with senators about committee assignments and leadership jobs.


Late last year, Hefner also floated the idea of running for Senate to succeed a retiring Boston-area senator — a possibility that caused further dissension within the chamber.
