Since 1915, City of Boston Credit Union has provided personal financing service and assurance for Boston and its surrounding areas. To become a member, just deposit $25, and you will officially own a share of the Union. This gives you equal standing on making Credit Union decisions; membership is not dependent on how much you have put into your checking or savings account. For futher information, visit a branch and speak with one of the representatives. There are additional locations in Boston's financial district and in Dorchester.
