The district said in its announcement that "Mr. Dion is looking forward to spending more time with his family in retirement. He will miss the students, faculty and staff of the District. Mr. Dion increased communication between the school and community while at Bay Shore."

The announcement also said that Dion is "entitled to full confidentiality regarding this personal matter" and that his separation from the district includes a retirement incentive equal to the balance of his salary and benefits for the remainder of the 2012-13 school year. But the district will not be responsible for his 2013-14 salary and benefits.

Appointed in May 2011, Dion's yearly starting salary was $229,000. Dion was lauded for adding Chinese as a World Language at the secondary level and helped facilitate community support for the redevelopment and acquisition of the Bay Shore Armory.

Frazier has served the Bay Shore School District as an administrator for the past 18 years. Beginning in 1995, Frazier was an assistant principal at Bay Shore High School and moved on to become the school's principal, a position he held for 11 years.
