Our School
I continue to be honored and excited to be a member of the Highland Middle School Family. As your principal, I look forward to each day to strengthening the relationships that I have with all of our outstanding students, families, teachers, and talented staff. Before taking on the role of principal, I served as an assistant principal for 5 years at Highland Middle School. Before arriving in Libertyville, I was a junior high school dean of students in Skokie, IL. I have also taught social studies and reading at the middle school level, as well as fifth grade.
Beyond the rigors of their academic program, we aim to instill in each student the essential principles of pride, respect, and responsibility so that they will become productive and contributing members of our increasingly global society.
High expectations, established by our qualified and dedicated staff, will be maintained while providing a safe, nurturing, student-centered community that fosters respect for individual differences. With this in mind, Highland's learning community continues to strive to exceed expectations. As evidence of this, Highland has been recognized as a National Blue Ribbon School of Excellence twice, in 1990 and 2010. In 2015, 2018, 2022 & 2025, Highland was recognized by the Association of Middle Grade Schools (AIMS) as an Illinois Horizon School to Watch. Also in 2015, 2018, 2022 & 2025, Highland was recognized at the national level by the National Forum to Accelerate Middle-Grades Reform as a National School to Watch.
I am also very excited about working with the active, involved parents who help make Highland an excellent place for our students to learn and grow. I look forward to doing whatever I can to support their efforts and encourage you to become a member of the Highland Family Association. Volunteering and participating at various events throughout the school year will also benefit not only your child, but all of the children at Highland.
As principal, I have many opportunities to serve our students, families, and faculty. If you ever need assistance, please do not hesitate to contact me.

With Hornet Pride,
