Douglas County's chief financial officer tendered her resignation on Tuesday, March 20.
Vicki Moore was promoted April 24, 2017, to the job overseeing the county's finance department.
"This was a difficult departure, and we wish her the best in her future career endeavors," said County Manager Larry Werner.
Douglas County is currently working through the fiscal year budget for 2018-2019.
Moore last appeared before the Douglas County Board of Commissioners on March 15 where she secured approval of an extension of the county's contract with its auditor and approval of a new financial policy.
