Today, Mr. LaCrosse and Mr. O’Hair had the chance to celebrate our amazing Altona staff with a coffee and treat cart surprise! Our team works tirelessly to support, teach, and care for students each day, and we love finding small ways to show our appreciation for all they do.

Moments like these help us pause, connect, and recognize the incredible people who make Altona such a special place for students and families. We are grateful for a staff that leads with heart, builds strong relationships, and shows up for kids every single day.

HISTORY MADE!
Please help us give a HUGE congratulations to Team Phenomenums, a team made up entirely of sixth graders (Eli, Tani, Will, Nico, & Amelia) who just accomplished something truly extraordinary at a 44-team VEX Robotics tournament!

Not only did they battle their way through an incredibly competitive field…
They SWEPT. EVERY. MAJOR. AWARD. 🏆

✨ Tournament Champions
✨ Robot Skills Champion
✨ Excellence Award

They are the first 6th-grade team in history to pull off this trifecta, a feat usually dominated by veteran middle school teams. Their teamwork, grit, creativity, and sheer determination were on full display from the first match to the final buzzer.

We are unbelievably proud of these young engineers. The future of robotics is bright!
