On the morning of the first day of school for the 2026-2027 school year, we mic’d up Mr. Spillman ‘95 as he greeted some of our students as they entered the school and wished them luck on the new year! Happy First Day St. Joe’s!

The Class of 2030 has officially arrived!

Today, we welcomed our newest Marauders and transfer students to campus for Orientation Day. From meeting teachers and classmates to exploring clubs, finding classrooms, learning the essentials of the Rowdies, extracurricular activities, and discovering what it means to be part of our Lasallian community, the day offered an exciting first look at life at St. Joe’s.

A special thank you to our Collegiate Ambassadors for helping every new student feel at home. We can’t wait to see what the Class of 2030 brings to the Brotherhood.

Tomorrow, the entire St. Joe’s community is back on campus. Let’s make it a great year!
