Accounting firm Marcum LLP has expanded its New England presence by purchasing New Haven, Connecticut-based Meyers, Harrison & Pia, LLC.

Terms of the deal were not disclosed.

Meyers, Harrison & Pia also has an office in Portland, Maine.

The firm’s 55 employees will become employees or partners at Marcum.

Meyers, Harrison & Pia’s New Haven employees will move into Marcum’s New Haven office, said Anthony Scillia, partner-in-charge of Marcum’s New England region.

“The office is well-positioned to get clients in New York City, Long Island, New Jersey, Connecticut and north of here,” Scillia said in an interview, adding that the acquisition gives Marcum a “presence in Maine.”

Marcum also has New England offices in Hartford and Greenwich, Connecticut, Providence, Rhode Island and Boston.
