🐾 New Service Dog Introduction

We are excited to introduce a valuable addition to our school community! Starting December 18, 2023, a specially trained service dog will be joining us.


Please note:

The service dog is not a pet and will be easily identifiable by wearing a vest.

When the dog is wearing the vest, she is working and should not be disturbed.

To ensure an undisturbed learning environment, the dog will primarily be stationed in the Guidance office.

The dog will always be leashed when entering or leaving the school premises.

Accommodations will be made for students with severe dog allergies.

Please extend a warm welcome to our newest member!
