JACKSON TWP — More than six centuries of experience will be headed out the door of Seneca Valley schools at the end of this school year.

Classes at Seneca Valley Senior High School have already ended for the year, and Wednesday, June 7, is the last day of school for children from kindergarten through 11th grade. With the end of the school year, 27 staff members at Seneca Valley schools, all of whom have been employed with the district for at least a decade, are retiring.

Combined, the retiring staff members represent over 665 years of service to Seneca Valley schools — nearly two-thirds of a millennium.

The list of retirees includes not only teachers, but also assistants, paraprofessionals, custodians and cafeteria staff, and high-ranking officials such as Ron Butschle, the dean of students at Seneca Valley Senior High who is retiring after 19 years.
