Proud to Be Part of Something Meaningful

Mountain States Construction is honored to have played a role in bringing St. Michael Plaza to life at Tri-Cities Prep.

This project is more than just concrete and craftsmanship — it’s a place for students, staff, and families to gather, reflect, and enjoy the beauty of their campus. The St. Michael statue stands as a powerful symbol, and the surrounding plaza creates a space that will be appreciated for years to come.

As spring and early summer roll in, we’re excited to see TC Prep students enjoying this incredible area — whether it’s between classes, after school, or just taking a moment to slow down.

Projects like this are why we do what we do.

Construction Excellence Since 1964
