  • 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.
