Merrimack Valley Credit Union was founded in 1955 as the Communications Workers Employee Credit Union in Lawrence, Massachusetts. As of March 2025, it rebranded � merging with Bridgewater Credit Union and RTN Federal Credit Union � to become BrightBridge Credit Union, serving over 115,000 members across Massachusetts and southern New Hampshire with roughly $2.3 billion in assets.

Merrimack Valley Credit Union has roots going back to 1955 as a small credit union for Communications Workers employees in Lawrence, Massachusetts, and grew into a multi-billion-dollar institution serving communities from southern New Hampshire down through the South Shore. In 2025, it joined with Bridgewater Credit Union and RTN Federal Credit Union to become BrightBridge Credit Union, offering checking, savings, auto loans, and mortgages under a new name but the same member-first mission.
