Our final End-of-Year Party was a wet and wild one with an EPIC water fight 🔫💦 that was perfect for the 90 degree day! 🥵☀️

It was a fun evening to remember, full of laughter and the community we love. 💙

Huge thanks goes to our tireless volunteers, who were filling water buckets and slinging snow cones 🍧 the *entire* time, to our generous food vendors, and our in-house DJ, Mr. Lewis, who always brings the heat. 😎

What a great way to send off the school year!

A few favorite snapshots from the eve of their graduation. ✨📸

Our departing eighth graders came together with their parents for a meaningful dinner where they shared their favorite memories and what's inspired them during their time at St. Mary's.

Honor Roll certificates were presented, and this year's Helen Hart Heneghan Scholarship Gift was also awarded to this year's deserving recipient, Alyssa Robinson. 🎉

The evening wrapped with a hilarious and touching walk down memory lane (thank you for the show, Mr. Garay!) that had our graduates roaring with laughter while they choked back some tears.

Is there anything better than sharing side-splitting laughs with your best buds?! 🤍🎓
