Welcome
A community where families show up for one another
Whether you're a longtime member of our school family or just discovering us for the first time, welcome.
For more than 160 years, St. Aloysius has been a community where families show up for one another and for our students in ways that make this place truly special. It is a place where students blossom while learning that God is at the center of everything.
As the world changes faster than ever, we remain committed to equipping our students with the knowledge, skills, and faith formation they need to thrive in the future that awaits them. We do this all together, as a community of love and support.

What our families say
More than a school, a family
“Our children transitioned to 1st grade and 4th grade this year and they are thriving! From smaller class sizes to the expectations for being a good person and a good student, it has been a great first year. They've been exposed to new learning opportunities from Spanish to computer programming to archery and numerous other things. The staff is extremely supportive of the kids and the families and truly want the best for everyone. We're extremely satisfied with our decision to enroll – it's truly been a blessing!”
Casey H.parent of two new students “We transitioned from the public schools. Since we've been here, there have been so many unexpected reasons we are grateful to have made the change. The curriculum is outstanding and my daughters are challenged in an appropriate way. The teachers get to know the students and address their needs due to smaller class sizes. Everyone has been so welcoming and there is a strong feeling of community among the families. Knowing what I know now, I would've definitely chosen to start my girls' education at St. Al's.”
Michelle Z.parent of two new students “I am so thankful for St. Al's because my granddaughters have found a place where they feel safe and loved. They both had a rough year last year with "hybrid learning" among other issues, like bullying. This year Reagan comes home and says that every day is a good day!”

News
Life at St. Al’s
St. Aloysius Catholic School is expanding to middle and high school!
We are excited to announce that we are starting with 6th grade next academic year and will continue to add one grade level each year until we reach 12th grade. This means that your child can now enjoy the benefits of a Catholic education from PreK to graduation at St. Aloysius! At St. Aloysius, we provide a place where students can blossom, where learning about God and his Creation is the center of everything, and where Christian morals and Catholic beliefs are developed and implemented for everyday living.
There's always enough snow!
With the sudden snowstorms this week, St. Al's students had just enough snow to build their first snowman of the season! Just look at those smiles!
A Scary Resemblance
On the Monday of Halloween, our St. Aloysius Home & School Association hosted a Halloween Extravaganza for our students! The afternoon was filled with games, treats, prizes and costumes. There was one costume that was so realistic, it was almost scary! Can you tell who the real Harry Potter is? Brady Dent (2) in the center, probably had you fooled!
