• Welcome to Our Class

     Welcome to Criminal Justice! 
  • Meet the Teacher

    I am Mr. Jack Grennes the new Criminal Justice Instructor at the A.K. Smith
    Career Center. I am a retired Hobart Police Department Lieutenant that served
    for 20 years. I started teaching criminal justice in 2004 at Hobart High School
    and taught part-time until 2016. I also taught at the Gary Area Career Center last
    school year. I am looking forward to sharing my experience with the students and
    to continue the program former instructor Officer L. Hood has developed over the
    years. Thank you Officer Hood for your commitment and dedication for making the
    program what it is today. I hope to continue your success.
