Trena Bledsoe pleaded guilty Sept. 6 in U.S. District Court in Greeneville to embezzlement and making a false statement in connection to a bankruptcy case.
Bledsoe faces up to 30 years in prison and a $1 million fine when sentenced. A sentencing date has not been scheduled.
According to court records, Bledsoe embezzled $105,900 from the credit union between April 2006 and August 2007.
Bledsoe began working at the Rogersville branch of the ACFCU in February 2003, rising through the ranks to head teller, vault custodian, member services representative, customer service representative and eventually loan processor.
The indictment states Bledsoe placed an electronic flag on the accounts of three credit union members, which prevented the credit union from mailing paper copies of their monthly statements to the members.
Prosecutors say Bledsoe then withdrew $27,000 from those three accounts for her personal use.
In March, Bledsoe filed Chapter 7 bankruptcy protection, but prosecutors say she failed to accurately fill out the statement of financial affairs form regarding her income, completely omitting any of the $105,900 she embezzled from ACFCU.
Bledsoe remains free on her own recognizance.
