Thank you for your interest in St. Catherine of Siena Academy!

Our mission is to educate young women to develop their feminine genius—their unique dignity, identity, gifts as women created in the image of God.

Established just under a decade ago, St. Catherine’s has grown into a thriving and rapidly growing school of 260 students. We seek to form the whole woman through a rigorous college preparatory curriculum, vibrant spiritual life, competitive athletics, and constant opportunities for service, leadership, and personal growth.

Above all, we strive for our students to be confident in who God created them to be: women of faith and dignity, women of ingenuity and intelligence, women of integrity and heart, ready to be a light in the world.

Come experience the SCA sisterhood!

“This high school builds the whole young woman intellectually, spiritually, and teaches the feminine genius approach to life. Amen!”


“A crazy amount of extra curricular options-basically if you are passionate about it [SCA] will find a way to help you bring it to fruition!”


“This school has a very strong faith atmosphere! The school is fairly new, but is starting to build a name for itself both spiritually and academically. The faculty and staff rock!”

Student, Class of '19

“This place (SCA) is about the best Catholic high school you can go to, in my opinion. The whole school isn’t just a school, but a family where everybody knows everybody. It’s a small enough school for that to be possible-and it’s really awesome! What makes SCA different is the people that make up the SCA family. There are no bullies and no one is mean to you. Everybody looks out for you and your teachers become friends….This place is really close to my heart.”

Alumna, Class of '12

“An excellent school that brings the girls together more like sisters rather than friends.”


“Even if there were 10 stars, I would still put 11!”


“An excellent community for families that want to stay involved!”


“An excellent community for families that want to stay involved! Everyone has a different opinion and all students, staff, and faculty are respectful of it. I have never been in an environment that was so inviting and welcoming. It is easy to find a home in this school because the staff genuinely care about you and want you to succeed. It really is a beautiful place and a great experience. I am very lucky to have gone through high school there.”


“Another thing I enjoyed about the school was the athletics. I played four different sports at this school and I had the same experience with all of them. The coaches really cared about me, not just how well I was performing and I was treated respectfully on and off the court. Further more, I felt that I was really being pushed physically and mentally during practice which I value in any activity.”


“As a graduate of this school, I can attest to not only the strong education I received from SCA but also the strong foundation I was given in which I could build my own faith upon. I felt fully prepared for the ‘real world’ both academically and spiritually.”
