We Invite You to Discover Your Full Potential!

High SchoolAs you join the Notre Dame de Sion High School community, you’ll feel a sense of belonging right away. It’s “cool to be smart” and your individual strengths and gifts are not only accepted, but celebrated where every moment is seen as an opportunity to grow spiritually, academically and socially. As a freshman, you’ll begin the school year with a retreat to get to know your new classmates-- many lifelong friendships have developed on this first trip together. A senior student or peer minister will be partnered with you on this retreat as you learn more about the wonderful Sion sisterhood.
