As an educator, I am continually impressed by everything Atrium accomplishes. It is a student-centered, diverse and vibrant community of engaged, inclusive learners where 21st century skills are being taught with creativity and dedication, and the faculty are among the best I have ever encountered. My son has learned and adopted much more sophisticated research and inquiry skills by middle school than my older children did in high school. He truly enjoys school and always is eager to tell me what he learned every day- and better yet, what it has stimulated him to consider and explore outside of school hours. Because I can compare it to the other schools my older children attended, I can attest to what a remarkable learning environment they have cultivated. My only regret is not knowing about it for my older children.

My daughter started at Atrium in Pre-K and is currently in kindergarten. Atrium is a wonderful school filled with enthusiastic, dedicated teachers who genuinely strive to teach children to love learning! It is a warm, welcoming community where each child's individuality is celebrated. The curriculum is rich and thoughtful. Even in Pre-K, students get weekly Spanish, music, art, library and PE. Atrium also has a great after school staff and lots of after school enrichment classes. My daughter loves school! She runs into the building each day, greeting the head of school, and giving high fives to the kids in the older grades. Atrium's mission is "Excellence with Joy," and it does a great job of living up to that mission.

We are very fortunate that both of our sons are at Atrium. As a family we, have been a part of the Atrium community for six years now. Atrium is a place where our boys are truly known, valued for who they are, and appreciated by all members of the community. What`s more is that they know this, and therefore they feel safe enough to take risks in their learning. Their educational experience is undoubtedly a rich and deep one, but what we, as parents, find equally, if not more important, is that they are happy going to school every day. Atrium is a place where students learn alongside a dedicated faculty who not only foster intellectual and academic curiosity but also cultivate a culture of kindness, empathy, innovation, and creativity. As parents, we are happy to be members of a welcoming, warm, inclusive community of adults including our fellow parents, teachers, staff, and administrators. Atrium`s middle school is a rare find; it maintains an progressive ethos while effectively preparing students for whatever lies ahead. Every year, our boys have been deeply engaged and appropriately challenged. We know (and are very thankful) that Atrium students leave Atrium understanding what it takes to be successful students, confident individuals, inquisitive learners, respectful members of a community, and productive citizens. Atrium is a true gem of a school!
