The Office of Central Services is a multifaceted agency of the Prince George's County Government providing government-wide, mission critical support services in the areas of facilities operations and management, building design & construction, real estate services, fleet management, and general services. After enrolling in the County's benefit plans, employees may only make changes to the plans either during the open enrollment period, which occurs annually (usually each October), and/or during the year, due to a family status change (i.e., marriage, births, divorce and adoption).
