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


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

SCA Parent

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


“[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

“[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.”


“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

“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.”


“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

“I was among one of the very first classes SCA ever had. As a pioneer and a student to be a part of the foundation of clubs and classes that continue today, I am beyond proud of how far the school has come. There were many ups and downs during my four years but an amazing experience overall. Today at college I still look back on and cherish my times at SCA, thankful for the connections, education and sisterhood I acquired. I am looking forward to seeing many more young women carry on the traditions my class and recent classes have set for the future.”

Alumna, Class of '14

“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.” 


Each summer here at SCA we host a variety of camps designed with future STARS in mind. Camps offered cover athletics, arts, science, and more.
