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 over 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!

“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!”


“SCA is authentically and unapologetically Catholic. It’s excellence in academics and athletics is rooted in its mission to pass on the beauty of the Catholic faith in a way that is relevant to the modern world. The result is a constant focus on the character and virtue of its students, challenging them to be the best version of themselves not just academically, but spiritually as well.”

“My family has had an excellent experience at this school so far. Beyond the beautiful new facility, I have been impressed with the teachers and the administration! They challenge the girls both academically and spiritually, they know them by name, and appear to have a genuine concern for each individual student. The school really feels like a family. As a parent, it is a blessing to me to know that my daughter is in such good hands when I drop her off everyday.”

SCA Parent

“This high school experience is like none other you can get anywhere. There is joy and comradery and the girls are happy and excel. They are being supported and encouraged by staff. You can watch a girl come in who had a bad experience elsewhere, bloom here and become a different girl in a short time. Can’t say enough good about it. Thank God the founders had this vision and followed through with it. Well needed and we are very thankful!”

SCA Parent

“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.”


“The school lives up to their mission statement by unlocking the feminine genius in the girls who go there and providing us with the opportunity to discover who we are meant to be.”


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


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


“[SCA] builds upon your faith and strengthen you academically throughout the four years in high school so that you are more than ready when you move on to college.”


“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.”
