What a wonderful job our Literary Magazine club did putting together this edition, under the direction of Mrs. Topel.  It's a  spectacular culmination of the works in creative writing and artistry from our talented Deerfield students throughout the school year.  Congratulations on a beautiful publication! Folio Literary Magazine 2026

Mr. Kinney and the Board of Education recognized important community partners at the June meeting.  The Watts Foundation have granted thousands of dollars to our schools and have impacted what our teachers can provide to our students.  We are so grateful for their ongoing generosity and support.  Also recognized were our Class II officers and our crossing guards for keeping us all safe.

A battle for the ages...adults vs. kiddos at our annual Field Day.  What a great day for some competitive fun!  Any guesses who won?

It's a tradition for our 8th grade class to take a trip to Washington, DC. They lucked out with some beautiful weather - sunshine and mild temperatures. Thank you to Mr. Young for all the time he put into planning the trip and making it look effortless. Thank you to all the teacher and parent chaperones, we couldn't do this trip without you!
