We can’t wait to see everyone in Little Rock! 🥋🔥

Our weather cancelation policy is to follow Grand Island Public Schools. Due to GIPS canceling after-school activities this evening (February 19), we will not have classes tonight. Stay warm and safe, everyone!

It’s never too early to start learning about self-defense awareness. We thoroughly enjoyed our time today with Girl Scouts Spirit Of Nebraska getting to share our love of practical self-defense with our future state leaders!

That feeling when you get to come back to train after the winter break . . .

So excited to start 2026 with you, CNSD families!
