The Lackawanna School District is losing its top two administrators to retirement in March.

Superintendent Nicholas D. Korach informed the district’s Board of Education his last day will be March 15, while the district’s longtime business official, Sameh Masry, is set to retire Friday.

Board members have turned to the district’s personnel director, Anne G. Spadone, to serve as interim superintendent through June 30. Spadone will get $500 per day in the interim role.

The board will conduct a national search for Korach’s successor, said Ronald Miller, board president.

“We expected he was going to retire. We just didn’t think it would be this soon,” said Miller, who described Korach as a “consummate professional.”

Korach, who made $156,116 in 2012, did not return telephone calls to comment.

A Lackawanna native, Korach, 59, spent more than 35 years with the district, where he began as a math teacher and later served as assistant principal, principal and in other administrative roles. He was appointed superintendent in 2010.

Korach’s contract was to run through June of 2014. The board last summer offered to extend the pact through June of 2015, but Korach declined.

Lisa A. Almasi, formerly director of finance in the Eden Central School District, was appointed assistant superintendent for administrative services and will succeed Masry, who has been with the district since 1979.

Almasi has vast experience and will be asked to develop and implement the district’s 2013-14 budget, he said. The district currently has a spending plan of about $45.3 million.

Almasi begins Friday and has a contract through February 2018. She will be paid $120,000 in the first year of the contract.

Spadone, who was an administrator with Erie 1 BOCES prior to coming to the Lackawanna district last year, is a candidate for the permanent job.

The board expects to find Korach’s successor by the end of June, said Miller.
