Alumna, Class of '18

“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.”


“My first day of freshman year was something I never expected, Saint Catherine 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 SCA 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.”

I know the friends my daughter has made will be her sisters for life.”
