Visit the RTN Credit Union Dorchester branch and find out how we can help you! Located across the street from the historic Baker Chocolate factory (now apartments) in Dorchester Lower Mills, the RTN Dorchester branch offers parking and is accessible by public transportation (MBTA subway, Red Line, Ashmont train, Ashmont stop—go to mbta.com for information). Members can use our two 24-hour ATMs, one in the lobby and one drive-up.  We encourage you to use our drive-up teller window during business hours. You can make the same transactions you would at the teller window inside the branch and you don’t have to leave your car! It’s a great way to stay warm and safe.

  • Notary Public and Securities Transfer Agent Medallion Program (STAMP) services available. Call ahead to make an appointment.
