Thrillshare Instant Alerts

The Thrillshare Instant Alert System is a form of communication that will contact parents through voice, email, and/or text messaging. This is different from our email broadcast system through Naviance which is used for more general school communication/information.

The instant alert system is used for snow days, delayed openings, and other emergency school issues and/or announcements.

To update your contact information (email, phone) please use the "Update Student Demographics" link under "Parents" on West Morris Mendham's website. The link can also be found below:

Contact information can be updated on a rolling basis.

Any issues updating your contact information should be directed to our Technology Department via our email address: itdept "at" A member of the WMRHSD Technology Department will then contact you for further assistance.
