1st year at SCA

“I loved every minute at St. Catherines! The friends I made there will always be a part of my family. This school taught me how to be a strong, intelligent, independent woman who is strong in her faith. I am blessed to say I got to experience SCA.”

Alumna, Class of '18

“[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.”


“Recently attended an event at this school – very beautiful!”


“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

“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.”


“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.” 


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

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
