On January 6^th, 2026 Trona High School officially opened its doors, marking a historic moment for our students, staff, and families. This milestone was beautifully commemorated on January 9^th as we gathered for our official ribbon-cutting ceremony.

It was truly moving to see our community come together at 3:00 p.m. to witness this new beginning. The energy and shared pride were a testament to the strength of Trona, and we are deeply grateful to everyone who joined us to celebrate. This building represents more than just classrooms; it is a symbol of our collective commitment to the future of our youth.

As we embark on this journey together, we want to extend a heartfelt thank you for your continued support and dedication. We look forward to the many memories and achievements that will fill these halls in the years to come.
