St. Cletus is a great school with a nurturing environment. Teachers are great, their tech is top notch and most importantly, my students love their school.

The Director, Stage and Prop Design, and everyone else should be highly commended for the performance of Willy Wonka Junior. Of course the kids were great and did a very professional job of acting, set change, lighting and music. I cannot say enough how much I enjoyed this play. I am grandmother to Emily Wiet, 6th Grade. Thank you
