The Maryland Association of County Administrative Officers was one of MACo’s first affiliate organizations. The Affiliate’s mission is to provide a network of county leaders to ensure that the highest quality programs and procedures are being utilized in Maryland’s counties.

The Affiliate elects officers at the MACo Winter Conference and its officers serve a one year term. Several events are held annually, including at both the MACo Winter Conference and the MACo Summer Conference, and at the annual Fall Administrators Conference. Many County Administrators are also members of the International City Managers Association and the National Association of County Administrators.
