The child is both a hope and a promise for mankind.” – Maria Montessori



Keystone Montessori School in Whittier CA applies the highest standards and educational methods developed by Dr. Maria Montessori. In Montessori, we understand your child’s inner world, which will create their personality in the future. The child-centered educational approach is based on scientific observations of children from birth to adulthood. We provide a well-prepared, inviting environment in a multi-age group setting, which fosters peer learning for children who are naturally eager to learn and initiate.
“Education is the most powerful weapon which you can use to change the world.” – Nelson Mandela.
At Keystone Montessori Preschool Whittier, we believe every child is a unique character who brings natural intelligence. They need a secure, caring, and inspiring atmosphere to grow and mature intellectually, physically, emotionally, and socially. We challenge and support children to reach their fullest natural potential in every developmental area by providing a safe, supportive, and challenging environment, while also meeting their critical emotional needs for respect, acceptance, inclusion, and security.
