Our daughter attended Notre Dame de Sion High School and it has been a wonderful experience for both her and our family. We were impressed by the academic rigor, the small classroom size and personal attention that she received, and the wide variety of accessible clubs, sports, and activities, and service opportunities that she could participate in. Most importantly, we were impressed by the Catholic foundation that was woven through curriculum and culture, and the impressive dialogue the teachers engaged in with their students. Our daughter has gained so much confidence, maturity, respect and love for learning and diversity. We feel she is ready for college as a well-rounded young adult, who will be able to problem solve and embrace what the world sends her way. Thanks, Sion!

Notre Dame de Sion provides students with a high quality, academic experience, which prepares them well for college! In addition, Sion's "Deep Dive" experiential programs are exciting, hands-on experiences where students are allowed to explore various interests. The faculty and staff at Sion get to know their students and truly care about their well being. This helps create a culture of mutual respect and inclusiveness for all types of kids. Our daughter loved her time at Sion and the friendships she made during those four years!!!

My daughter has thrived at Sion High School! She has been given many opportunities to have new experiences, try new classes, and become a leader. She has had multiple opportunities to travel and work within the community, including taking pictures on a sports field! This smaller school has all the opportunities of a larger school. The administration and teachers care about the students. They listen to feedback and make adjustments while continuing to maintain high standards. Sion has wonderful traditions, and as my senior is nearing graduation, we are figuring out how to stay involved with this gem of a school!
