About the Administrators:

Harper welcomes you as a partner in the education of your child. Please feel free to contact us anytime as our door (or email) is always open.

Aaron Dubnow, Principal


I am so thrilled to be starting my 2nd year as Principal at Harper. After graduating from New Trier High School, I attended the University of Illinois (Go Illini!) majoring in Education with a middle school endorsement. I earned my Master’s in Administration and Supervision from National Louis University. 

I began in District 39 teaching a combination of science, math, and social studies to 8th graders at Wilmette Junior High School for 6 years. Outside the classroom, I have been the coach of the cross country and track and field teams, and a sponsor of student council. From 2015-2019 I was the 5th Grade Level Administrator at Highcrest Middle School.

Outside of work, I enjoy spending time with my wife, family, and friends, running, and going to sporting events - especially at Wrigley Field.

Elena Ryan, Assistant Principal

Elena Ryan is starting her 4th year as the Assistant Principal and will be full time at Harper this school year! Prior to her position in D39 Elena served as a K-8 Department Chair for Fine Arts and PE for the two years in Glenview, District 34. Her teaching career was as a General Music and Choir teacher for eleven years at Attea Middle School in Glenview. In addition to being an educator,  she is a consultant for Music Industry companies. Through that work she has enjoyed presenting at conferences around the country on ways to integrate innovative programs/technologies into a music classroom. Elena lives in Skokie with her husband and two kids where she enjoys cooking and chasing her boys around the yard.
