BayCoast Bank has bought a 48-year-old Somerset-based insurance agency and folded it into the bank’s insurance subsidiary.

E.P. Tremblay and Sons Insurance Agency started operating under the BayCoast Insurance banner on May 31, the Swansea-based bank said in a statement.

“We are proud to welcome E.P. Tremblay Insurance to the BayCoast Insurance family,” Patrick D. Long, president and CEO of BayCoast Insurance, said in a statement. “For more than 48 years, E.P. Tremblay has offered comprehensive insurance coverage to members of our local communities. We look forward to continuing to provide the customized solutions and service they have come to expect.”

The acquisition adds to the bank’s network of insurance offices in Fall River, Somerset, Swansea, Seekonk, and Fairhaven and Tiverton, Rhode Island. However, the bank isn’t acquiring E.P. Tremblay’s real estate, accounting and payroll services.

“With our aligned cultures and values, the decision to join BayCoast Insurance was an easy one to make,” Mark Tremblay, president of E.P. Tremblay, said in a statement. “It has been a privilege to have served my insurance customers throughout the years, and I am confident they will enjoy an exceptional level of service with BayCoast that is second to none.”

This is the second acquisition for BayCoast Insurance in recent months, following its purchase of Hadley Insurit Group in Fall River at the end of last year.
