IMPORTANT ANNOUNCEMENTS / UPDATES


Update from Mrs. Shanks

July 10, 2026

Good afternoon Dumbarton families,

I hope you have been enjoying your summer! As we prepare for the upcoming school year, we are ready to “turn the page” and start “the next chapter” with our Lions.  Our theme for this year is focused on our story, our school and our “pride” (family) of lions and “pride” (satisfaction and honor) in our students.

Welcome to our new Lion students and families! I typically send school communications on Fridays so that you are informed regarding school activities, and reminders. Most information will be found and updated regularly on our website: https://dumbartonms.bcps.org

To help you prepare for the upcoming school year, we wanted to send you two reminders today. First is our link to school supplies for this year, and second is our summer reading information.

1. You can find our school supply link here and on our website: DMS Supply List 2026-2027.pdf 

*If you would like to purchase a planner from the PTSA for $5, please read and complete this form: Interest Form for Purchasing a 2026-2027 Planner for Your Student from the PTSA  – Fill out form

2. Summer reading assignment/ information for all students: Dumbarton 2026 Summer Reading All Grades.docx 

If you have any questions we can help you with, don’t hesitate to reach out! Our summer office hours are Monday-Thursday (in-person) 8 AM- 3 PM and Friday (virtually via phone or e-mail) 8AM- 3PM.

In the meantime, we continue to plan for the next school year and can’t wait to share more information with you later this summer. Keep your eye out for important e-mails and a postcard in mid-August. Enjoy your summer!

Mandy Shanks

Principal, Dumbarton Middle School
