We may be on break…but still wanted to send some Christmas Cheer! ♥️
Our 8th Grade Student Council Members had the privilege of visiting the WI Humane Society yesterday. Over the past few months, they worked hard collecting donations and wish list items to create a special Christmas delivery. The joy on their faces says it all — giving back and making a difference... is truly what this season is about.
If you’re looking to brighten your home with a furry friend this holiday season, the WI Humane Society Saukville Campus has adoption hours throughout the week and would love to help you find your perfect match. We are so honored to support such an incredible organization and incredibly proud of our students’ compassionate hearts. 🐾❤️
These kiddos had an extra special start to their morning — they got to “Ride to School in a Police Car” thanks to our Key Event silent auction! 🚓✨
What an unforgettable way to celebrate the last day before Christmas break.
A huge thank you to @port_washington_pd_wisconsin ...for making this experience so exciting and memorable for our students. We are so grateful for your support and for helping create smiles that will last well beyond today!
