National Custodian Day 2025

Today we pause to celebrate and recognize our incredible custodial staff. Their hard work, commitment, and dedication does not go unnoticed. From keeping our classrooms and hallways clean and safe, to ensuring that every event and activity runs smoothly, our custodians are an essential part of the success of Calvert ISD.
They serve our students, staff, and community with excellence each and every day, and we truly couldn’t make it without them.

Thank you Ms. Lott, Mr. Cargill, Mr. Mendoza, and Mr. Pride
