Last week was all about our 8th graders, but this week it was our littlest graduates’ turn to shine! πŸŽ“πŸ’™πŸ’›

Though they may be small, they have accomplished so much this year. We are incredibly proud of all they have learned, the friendships they have made, and the confidence they have gained along the way.

Congratulations to all our littles! We look forward to seeing you next year! ✨

55 years later and the memories are still going strong!

Members of the St. Mary School Class of 1971 recently gathered for a mini reunion at The Harp & Hound in Islip.

It’s always special to see the lasting friendships and connections that began at St. Mary School and continue decades later.

Once an SMS student, always an SMS student. πŸ’™πŸ’›
