🐻💙 Arrival is always O-SO FUN! 💛

We love starting each school day with our Grizzlies, but keeping everyone safe is our TOP priority! 🚗🚸

As you arrive on campus, please remember to slow down, follow all traffic laws, obey traffic signs, use designated drop-off areas, and watch for pedestrians. A few extra moments of patience can make a BIG difference in keeping our students, families, and staff safe.

Let’s work together to make arrival not only O-SO FUN, but O-SO SAFE! 💙💛

Safety is EVERYONE’S responsibility! Thank you for helping us protect our Grizzly family! 🐾



💛🐻💙
