San Bernardino County Administrative Officer Greg Devereaux announced several management changes Thursday, including the hiring of two administrators who worked under him in Ontario.

Mary Jane Olhasso was appointed Economic Development Agency administrator, a week after Mark Dowling, who had been in the position for two years, resigned suddenly. Olhasso held similar duties in Ontario, where Devereaux was the longtime city manager until he took the county job in February.

Another former Ontario official, Loron Cox, was appointed assistant county administrator for finance and administration. Cox retired as Ontario’s finance director a decade ago.
