Office of School Safety


Letter from the Chief:

Thank you for visiting our safety website! We hope you will find our site helpful in locating employees and services that address your needs.  OSS is a dual agency comprising School Police Operations and Incident Management. Our office is committed to providing a safe school environment for students and staff.

Every student deserves the opportunity to reach his/her full academic potential in a safe, productive classroom. Through effective school/community partnership with principals, teachers, students, parents and citizens this can be achieved.  We encourage you to become involved in your neighborhood school by volunteering, joining a Safe Corridors Program, or any other activity that will improve safety in and around our schools.  Please take a moment to explore our services and partnerships.

Again, thank you for visiting our site and for your interest in school safety.
