Many of our instructional staff are still active in the field. This is especially true of the instructors in our POST training program. Our faculty comes from all levels of the criminal justice system, from officers to retired chiefs, attorneys to judges. This is how we are able to bring the most up-to-date information and techniques to the Administration of Justice student.
