Memorial Health Credit Union is a 42 year-old not-for-profit financial cooperative established in 1972. Memorial Health Credit Union has merged with several area credit unions and now includes these former entities as part of the MHCU family: Savannah Seaboard, Health Employees, and Coastal Georgia Credit Union. It’s easy to join the credit union and enjoy the benefits of low interest rates and fees. First, you must be a resident of Chatham County or an employee of one of our Field of Membership.
