Bluestone Bank, Bridgewater Division, Pembroke Branch

Southeastern Massachusetts will see familiar bank branches with a new name as the merger of two longstanding mutual banks creates a new bank.

Bridgewater Savings Bank and Mansfield Bank completed their merger on Oct. 1, forming Bluestone Bank. The bank said in a statement that customers would receive the same commitment to their financial needs, along with more banking locations, more ATMs, new products, services and technology advances.

“Its expanded size makes it a better bank and allows it to be a better community leader too, with a greater capacity to give back to its neighborhoods,” the bank said in a statement.

Bridgewater Savings Bank’s CEO, Peter Dello Russo, will be Bluestone Bank’s CEO, and Mansfield Bank’s leader, Meg McIsaac, will be the bank’s president.

“We are very proud of our heritage and the trust we’ve earned for over 130 years. Bluestone Bank is here to support your goals and needs to ensure your financial success, every step of the way,” Dello Russo and McIsaac said in a joint statement. “Our foundation is built on community values and shared responsibility, and you’ll see it in the way we do business.”

The bank said Bluestone’s commercial banking division would serve more local businesses in an expanded market area with larger loans, and the bank also has a mortgage lending team and wealth management division, Bluestone Wealth and Trust.

Bluestone Bank has about $1.2 billion in assets and 12 banking offices and 2 loan production offices in southeastern Massachusetts, with branches in Bridgewater, Easton, Lakeville, Mansfield, Norton, North Attleboro, Pembroke, Plainville, Raynham, Taunton and West Bridgewater.
