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!

“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.”

“Beautiful school!”


“Karen Ervin is a remarkable principal! She is a good administrator, but even more importantly, she is an excellent role model for the students. She is strong, confident, and a woman of tremendous virtue. She is unafraid and doing everything in her power to raise strong, Catholic women who will go out and ‘set the world ablaze’!”

SCA Parent

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


“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 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.”

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

SCA Parent

“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!”


“My first day of freshman year was something I never expected, Saint Catherines just felt like home. The atmosphere, staff, and the student body were all so amazing. I knew from the second I came to the school that it was where I was meant to be. I am currently a senior and my experience so far has been one too remember I have grown mentally, physically, spiritually and my journey has been one to remember. I love Saint Catherine of Siena and all the girls I have met are truly going to be my sisters throughout my life, its an amazing school and is a place I will call home forever.”

Alumna, Class of '18

“This school has a very strong faith atmosphere! The school is fairly new, but is starting to build a name for itself both spiritually and academically. The faculty and staff rock!”
