COOPERSTOWN – Sarah Spross, an assistant superintendent in the State of Maryland Department of Education, will become the Cooperstown Central School District’s new superintendent March 1 – or sooner. “We hope sooner,” said school board President Tim Hayes this morning. He said it would give her more time to be introduced to her new responsibilities by the interim superintendent, Romona Wenck. Spross, originally from Millbrook, Dutchess County, will succeed Bill Crankshaw,who resigned in August to lead the Greater Johnstown School District in his hometown.
