Our History Mid Carolina Credit Union was chartered and opened in 1961 as a benefit for the employees of the Dupont May Plant. Over our five decades of operation, Mid Carolina Credit Union has grown from a single employee operation based in the plant guardhouse to a financial institution with four offices, four ATM’s, account access via telephones and computers and a staff of more than 40 employees. Mid Carolina Credit Union’s charter has been expanded from our original sponsor to include multiple employment groups and anyone who lives, works or attends school in Kershaw or Richland County.
