Jim O’Connor is a different teacher, he is a strict Vietnam veteran and tenured math teacher whom you don’t want to mess with. He sports a short, military-style haircut and has sharp, watchful eyes that regularly scan his classroom.After years in the military, he has an authoritative voice that catches all of his students’ attention. He also doesn’t put up with much out of any rowdy and restless teens in his high school classroom. He has no kids and wife, but when the students know his secret , they were touched so much and also so proud that to be his student!!
