Best Buddies enjoy a Maine Mariners Game and STEM Fair!

Greely Middle School’s 4–8 Best Buddies Club had an amazing day at the Maine Mariners game and STEM Fair! Students had the chance to cheer on the Mariners, explore hands-on STEM activities, and most importantly spend time together building friendships. Experiences like this show how powerful inclusion and community can be when everyone comes together.
