One of our favorite senior traditions wrapped up the school year today, the Senior Water Fight!

There were lots of laughs, plenty of splashes, and memories that will last long after graduation. We’re so glad everyone had a great time. Congratulations, seniors! You will be missed, and we can’t wait to see all the amazing things you do next.
