Welcome to Berlyn Elementary School!  As the proud principal of Berlyn Elementary school, I would like to welcome you to team Berlyn!

Berlyn Elementary serves students from Transitional Kindergarten through 6thgrade.  We currently have approximately 745 students who are served by 32 dedicated certificated teachers.  You will frequently hear students and staff share our vision, which is to: “Be Intrigued, Be Innovative, Be Inspired, Are You In3?”

During the 2018-2019 year we celebrated many achievements. We continued our PBIS (Positive Behavior Interventions and Supports) implementation, were honored with the Healthier US schools Challenge Gold Award, and expanded our technology distinctive to ensure 1:1 devices in all 3rd-6th grade classrooms and 1:2 in primary classrooms.

As we move into the 2019-2020 school year, I look forward to being a partner with you in your child’s education.  We will work to ensure students are becoming life-long learners through a focus on our academic program, ensuring students are physically and emotionally safe, provide extended extracurricular opportunities, and fostering a love of learning. 

As a principal, I am here to serve the students, staff, families and the community.  I invite you to join our various site parent teams to help have a voice in offerings here at Berlyn! Please also feel free to communicate with me if you have any questions or suggestions for Berlyn! I can be reached by calling the front office at (909)986-8995 or via email
