  • Students Spoke at the Welcome Home Vietnam Veterans Celebration
    We want to recognize three of our upper elementary students who had the opportunity to give speeches on March 25th on behalf of the school and Veterans Heritage Project at the Welcome Home Vietnam Veterans event, honoring those who served during the time of the Vietnam War. Ava, Joseph, and Luke volunteered to give their speeches and they did an amazing job, with little guidance from their teachers. Rory and Arastyn volunteered to give out honorary pins. Congratulations and well done to these students!

About the school

Serving the East Valley for 40 years

Montessori International School was founded in 1982 in Gilbert. It originally opening as a primary school out on McQueen Road and Baseline. The school was extended the next year to the Gilbert Road address in Mesa where the office and two primary classes are currently housed. In 1984 MIS expanded further to include the Brown Road campus, where one toddler, one primary and the elementary classes are now located.

Hundreds of children have grown and developed through MIS’s programs, and many now contribute as adults in the community. The school currently occupies the two campuses located on Gilbert Road and Brown Road, and an infant community next to the Brown Road campus (opened in 2003). Montessori International School has grown from its first primary class to the present:

  • an infant community
  • a toddler community
  • three primary classes
  • one lower elementary class
  • one upper elementary class

The MIS teaching staff is led by the founder, Therese Kestner, B.A., M.Ed, AMI certified and specializing in learning disabilities. She has taught and directed Montessori schools for the past 50 years. We are delighted to bring these facilities to life each day with the personalities of our staff, our students, and the many others that combine to make up the Montessori International School community.

School Philosophy

Our classrooms are places where children are given the opportunity to achieve academic and personal success. The goal in these environments is to support the development of one’s self. The principles put forth by Dr. Montessori are utilized in all classrooms – infant, toddler, primary and elementary. Each of the teachers in these classes use their training to create environments that cater to the characteristics of the children in their classrooms.

We strive to create an environment that:

  • encourages children to create themselves through exploration.
  • provides children with the tools that they need to achieve independence.
  • fosters an appreciation for learning by nurturing sparks of curiosity, creativity, and intelligence.
  • encourages children to develop the skills that they need to become contributing members of the larger society.

Our hope is to provide an opportunity to each student that will lead to their better understanding of the world and the roles that they play in it.

Affiliations

The infant, toddler, and primary classes at MIS are affiliated with the Association Montessori International (AMI). This training and accreditation organization was founded by Dr. Maria Montessori herself in 1929. The teachers in these classes have finished the AMI training for their specific age groups, and participate in ongoing teacher education in the form of conferences, refresher courses, and meetings with other AMI teachers in the area.

The elementary teachers have met the requirements for the Arizona State teaching credential. They also participate in ongoing education. Montessori International School is licensed by the Arizona State Health Department.
