She was recognized by an independent panel of community leaders for her efforts to streamline the county's phone billing.
Eichelberger, who had been processing 2,000 pages of phone bills a month, now receives phone bills on a compact disc, reducing the time she spends on phone bills from five days a month to one day a month, saving the county $5,000.
The new billing system provides an accurate way to track calls from each of the county's 556 phone lines.
Eichelberger, 26, of Hagerstown, said she was "very, very shocked" by the award after County Administrator Rodney M. Shoop surprised her with the announcement.
"Congratulations. You're doing a fine job," said County Commissioners President Gregory I. Snook.
"I commend Cindy for an outstanding achievement," said her boss, Finance Director Debra Bastian.
Eichelberger, a graduate of Clear Spring High School, is studying accounting at Hagerstown Junior College.
