As part of Affton's Community Day of Service a few of our second grade classes (Sutterfield, Buss, Garner) made inspirational keychains to be donated to Rainbows for Kids to help kids going through long hospital stays or tough cancer treatments. What a great way to spread some joy! 🐾❤️🎉🌟

Today’s Affton Community Day of Service was extra special! Our Gotsch 4th graders visited Mesnier Primary to read with our kindergartners, proving that you’re never too young to lead and give back. ❤️🐾
Seeing our older students mentor their younger peers is what being a Cougar is all about!
