Founded in 1998, the school is located in a beautifully renovated mill building in North Chelmsford. Our spacious classrooms create a peaceful and relaxed learning environment where children love to explore and learn, guided by experienced and certified Montessori teachers. Our facility includes a library, art room, and multi-purpose room. Every student enjoys art, music, and Spanish as part of their Keystone experience.
Whether children are developing their focus and fine motor skills, mastering letter sounds, or adding four-digit numbers, they enjoy learning through hands-on experience with superb materials. Our teachers guide each child through the curriculum in a series of success-oriented steps.
All of our Head Teachers are Montessori certified, and have been teaching for years. Because Keystone is a great place to teach, our staff retention is outstanding.
Keystone offers half day and full day programs for children age 2 years 9 months through kindergarten. Our elementary program goes through grade six. All of our programs are five days a week. Call and schedule an appointment to visit Keystone. It’s the greatest gift you can give to your child.
