“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

“I have been very impressed with the teachers at this school. They both challenge the girls academically and show true concern for them on a personal level as well.”

SCA Parent

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


“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.”

SCA Parent

“[Teachers] care about the success of each student. They come early to help students and stay after school if necessary. They are a super dedicated faculty.”

SCA Parent

“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.” 


“I LOVE this school. The teachers are excellent. Because the students are so friendly, it’s easy to fit in and make friends even if you have had a tough time at other schools. There is virtually no bullying and it is a very friendly, positive environment. Highly recommended.”

Alumna, Class of '17

“The community service, the focus on virtuous living, and the sisterhood really instills compassion and respect for all of humanity.”

SCA Parent

“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.”
