Message from our Founder
When I first discovered Montessori, I recognised a school experience I would have loved as a child: calm classrooms, adults who listen, and real work that builds confidence. In 2010 we opened CMMIS to offer that experience in Chiang Mai—rooted in Thai culture, spoken in English, and faithful to Dr. Montessori’s original approach.
With two of my own children in the school, my promise is simple: a safe, beautiful environment; guides who observe each child and present lessons at the right moment; and a strong partnership with families.
We value respect, order, and joyful effort—qualities that serve children in any culture and any later school. If you are exploring CMMIS, please visit. See a classroom in action, watch the concentration, and notice the kindness. We would be honoured to welcome your family.

Our Montessori Approach
Faithful to Montessori, practical for today’s families
We follow the AMI Montessori framework with trained guides, mixed-age classrooms (3–6 and 6–12), and a protected three-hour work cycle. Children move purposefully, choose work with guidance, and practise until mastery—building concentration, order, independence, and social responsibility.
Academic foundations are strong and concrete: hands-on materials for mathematics, language, geography, biology, and geometry lead naturally to abstraction. Children learn grace and courtesy, care for their environment, and how to solve problems respectfully.
For families new to Montessori: think structured freedom. Adults prepare the environment and give clear lessons; children practise with increasing responsibility.
