The Derry Township Middle School Parent-Teacher Organization (PTO) is an active service organization involving parents who help at school and at home. The PTO works in cooperation with the Hershey Middle School administration and faculty to enhance the school's learning community. PTO meetings are usually held on the first Thursday of each month during the school year. These meetings are open opportunities to learn more about the PTO and to find out how you can lend a hand. If you have any questions contact HMS President Tracey Bemis, or membership questions contact Cindy Jackson. .
