“Beautiful school!”


“I loved every minute at St. Catherine! 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

“This school is not only college prep, it is life prep. I know that my daughter is being educated to go out and make a positive difference in the world. She will graduate with the confidence and courage to lead wherever she goes in life. I love the principal, the teachers, and the families. It is such a blessing to be a part of the SCA Family. I know the friends my daughter has made will be her sisters for life.”

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

“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.”


“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.”


“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!”


“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

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