School Notes

  • School Motto: Education begins at birth.
  • Our classrooms are places where children are given the opportunity to achieve academic and personal success. The goal is to encourage the development of a love for learning in each child. Using the principles put forth by Dr. Maria Montessori, our teachers carefully prepare environments in order to:
  • encourage children to create themselves through exploration.
  • foster love for learning by nurturing sparks of curiosity, creativity and intelligence.
  • provide children with the tools that they need to achieve independence.
  • encourage children to develop the skills that they need to become contributing members of the larger society.
