Established in 1994, Keystone Montessori School was designed to "nurture and develop the unique capabilities of all its students allowing them to find a positive, productive place in the larger community."

The school's curriculum includes educational courses for children ages 3 months to 14 years old.

Early education begins with the Parent-Infant Program and extends to the Toddler Program, designed for children "who are ready to be without a parent for three hours."

Next, children can attend the Primary Program, designed for those aged 3 to 6 years old, where students engage in "practical life exercises" and develop their sensory skills.

There's also a two-tiered Elementary Program,"which is divided into two levels: a junior class for children ages 6 to 9 and a senior class for 9- to-12-year-old students. 

Finally, there's the Adolescent Program for students 12 to 14 years old, which promises to move middle school aged kids "toward self-sufficiency, self-respect, and self-confidence while appreciating our human interdependency, working in joyous collaboration, and making meaningful contributions to their society."

Keystone also offers Day House, a fee-based program for before and after school care — as well as crafts, games and play time — for kids age 5 and up.
