I was a High School Principal and Mathematics teacher for almost 38 years in three different school districts in Pennsylvania.  I was discharged from the military in December 1971 and started teaching on January 2, 1972, at Tyrone Area Jr/Sr High School, Tyrone, located near Penn State University.  The administration at Tyrone School District treated me well as evidenced by the fact I was named the Mathematics Department Head at Tyrone in 1978 even though I was not the most senior teacher in the department..
