Mrs. Bartosh
Welcome to Berlyn Elementary School!

It is both an honor and a privilege to begin my 8th year as the principal of Berlyn Elementary—a place that has been my “home away from home” for nearly 19 years! I am thrilled to continue this journey alongside our dedicated staff and wonderful community. Joining me in leadership is our new Assistant Principal, Marcella Schwager and Berlyn welcomes an additional Assistant Principal, Gianna Roca. Together, we are committed to working collaboratively with students, families, staff, and community partners to ensure every child thrives.
As we step into the 2025–2026 school year, our passionate educators are ready to engage students in meaningful academic experiences, cultivate a love of learning, and support their physical and emotional well-being. This year, we will continue to provide extended extracurricular opportunities and a strong academic foundation to help our students become lifelong learners.
You’ll often hear our school community say:
“Be Intrigued, Be Innovative, Be Inspired. Are You In³?”
This vision is at the heart of everything we do at Berlyn.
As your principal, I am here to support our students, families, staff, and broader school community. I encourage you to get involved by joining one of our many community leadership teams, where your voice and partnership can help shape the student experience.
If you have any questions or would like to connect, please don’t hesitate to reach out. I can be reached at the front office at (909) 986-8995 or via email at katie.bartosh@omsd.net.
Here’s to a fantastic school year!
Warm regards,
Katie Bartosh
Principal, Berlyn Elementary
