The Dowd Agencies and the J. Raymond Lussier Insurance Agency announced they have merged their operations and will be known as Lussier-Dowd Insurance. The merger and addition of a branch in West Springfield expands Dowd’s footprint to six offices located throughout the Pioneer Valley. The new office, located at 181 Park Ave., is minutes from Routes 5 and 20, and Interstates 91, 291 and 391. An open house will be planned at a later date.
