Mission

To provide educational services to children ages 2 years & 5 months to children ages 6 years old. The montessori curriculum is based on the idea that preschool children have an "absorbent mind," able to incorporate lessons by active interaction with the prepared environment, learning materials and multi-aged peers. The classroom is divided into four distinct areas: practical life, sensorial, mathematics and language.
