YANKTON, S.D. — The head of South Dakota’s mental health hospital in Yankton is resigning just a year after taking the job.

A spokeswoman with the Department of Social Services says Human Services Center Administrator Troy Jones announced his resignation Monday for personal and family reasons. His last day will be Aug. 31.

Jones took over as administrator in May 2016. He vowed to improve employee safety and morale at the center, which has struggled with turnover and staff shortages.

The Argus Leader (http://argusne.ws/2rKhIOE ) reports Jones’ departure leaves state officials searching for the center’s fourth administrator since 2011.

Gov. Dennis Daugaard had expressed support for Jones and encouraged critics to show patience as he addressed the hospital’s challenges.

Daugaard’s chief of staff, Tony Venhuizen, says the governor is sorry to see Jones go.
