Summer Info (Office Hrs/Construction/Access)

DBO Family,

Well here we are….. the last day of school. As we wrap up 2021-2022, we are excited for all the construction projects taking place over the summer that will create a safer, healthier teaching and learning environment for the 2022-2023 school year. Please read the important summer notes below.

From all of us here at DBO we wish you a safe, healthy and fun summer and we look forward to seeing most of you in September.

Summer Notes:

  • The office will be closed Mon June 27th and reopen Tue July 5th.

  • Typical office hours are Mon through Thu 8am to 3pm and Fri 8am to 1pm.

  • There will be days throughout the summer that the office is closed due to construction.

  • We advise that no one comes to the building including parking lots/playgrounds all summer.

  • If you need assistance and the office is closed, please call the central administration office at 973-627-8200
