Jon Hallmark - Principal
I am proud to be an administrator in a district that is committed to preparing its students for the 21st century. Prior to taking on the role of Principal, I served as the Assistant Principal for five years here at Highland Middle School. Before arriving in Libertyville, I was a Dean of Students at the junior high level in Skokie, Illinois. I have taught social studies and reading at the middle school level. I have also taught 5th grade at the elementary level.

As Principal, I have many opportunities to serve our students, families, and faculty. If you are ever in need of assistance, please do not hesitate to contact me.
