Why Families Choose Keystone:
“Keystone has been a wonderful place of learning for our child for 4 years. We love the community and the staff. His teacher is amazing, hard working, patient and kind. Our child needs the ability to learn social emotional skills at the same rate as his same aged peers, but academic at a faster pace. Traditional elementary school was not a good fit. He fits in at Keystone. We are thankful the school has the ability to continue to 8th grade so our child can have the best opportunity possible.”
— Elementary Parent“We feel so lucky to have found Keystone. Our daughter is in the toddler program and our son is in the primary classroom, and we could not be happier with our choice. Keystone offers a nurturing, high-quality education for children from 22 months through eighth grade, which made it especially appealing for our family. The school is small, welcoming, and built around a close-knit community where children truly feel known and supported. The teachers are incredibly kind, attentive, and deeply invested in each child's growth. I toured about four different schools before choosing Keystone, and this was the only one that gave me that genuine warm, reassuring feeling. I strongly recommend Keystone to parents looking for a caring, developmentally supportive school that guides children from early childhood through middle school.”
— Toddler & Primary Parent“We are so lucky to have our daughter at Keystone. Not only is our two year old learning valuable life skills that we see in practice every day, but she loves going to school. I would highly recommend Keystone and their parent-infant program to start off your child's learning journey.”
