School Messenger is the program we use to make all-calls to parents. Presently the program is not functioning properly as it is inconsistently contacting mobile phone numbers, devices, and email accounts. If there is a school cancellation before the program is fixed, you can view our website, Twitter page, and Facebook profile for up-to-date calamity notices.
The company is aware of the problem and estimate it will be fixed in 5-6 days.
