The $3 billion Mid-Atlantic Corporate FCU announced this week there's been some turnover on its board.

Virginia Williams, CEO of the $121 million Jersey Shore FCU in Northfield, N.J., resigned effective Dec. 31 and was replaced by Alison DeTuncq, president/CEO of the $612 million University of Virginia Community Credit Union in Charlottesville, Va.  

Mid-Atlantic President/CEO Jay Murray said Williams' departure from the board is in preparation for the future as the 40-year credit union executive eyes retirement. Williams has been Jersey Shore's CEO since 1986, and worked her way up to the corner office from a teller position at the $31 million Bridgeton Onized FCU in Vineland, N.J.. She was appointed to the corporate's board of directors in 2006 after one year on the supervisory committee.

DeTuncq, who has served on the 900-member Mid-Atlantic Corporate's supervisory committee since Dec. 2011, was appointed by the board to replace Williams.

She will bring board representation from the state of Virginia to the Middletown, Pa.-based corporate, which merged VACORP approximately one year ago.

DeTuncq began her credit union career in 1988 as a branch manager at UVA Community and was named president/CEO in 1998.
