One year ago, we cut the ribbon on our book vending machine. In that year, students have taken home over 800 books freely, consistently, and with pride. Small systems, when designed well, change daily habits. This one helped make reading visible, exciting, and normal.

Proud to partner with our incredible PTA to spread holiday cheer at Manorhaven Elementary! Together, we delivered hot cocoa door-to-door, bringing warmth and joy to our students and staff. Community partnerships like this make our school stronger.

Different system, same leadership demands. What works in a platoon often works in a school because both are human systems built on trust, clarity, and culture. Curious: Which non-education leadership books have shaped how you lead?

The 2026 Commandant’s Reading List was just released. In the USMC, it helps develop leaders. clarity, character, and accountability. Now that I lead a school, it’s obvious: more principals should be reading from this list. Here are 5 books I’d recommend for school leaders 👇

Schools thrive when joy and connection are part of the daily experience. Shared moments like this aren’t just fun — they’re strategic. They build a sense of belonging
