THM International School was founded by Dr. Prachumporn Suwantra, a respected leader in early childhood education with nearly five decades of experience.

Built on a deep understanding of how young children learn best, THM creates a nurturing and inspiring environment where every child feels secure, valued, and encouraged to explore.

Our approach blends the American curriculum with Montessori philosophy, combining structured learning with hands-on, self-directed experiences. This balanced foundation supports each child’s intellectual, social, and emotional growth.

At THM, education goes beyond academics. We nurture confident, independent learners who are ready for the future.

Belonging - The House System

When your child starts at THM International School, they're automatically enrolled into a House.
This is a great way for them to make new friends and feel part of a community.
The House System is based on values of teamwork, community, inclusivity, and competition.
We have four Houses, each is named after a tree. They are:

Our Programs

At THM International School, we combine the American curriculum with Montessori philosophy to support the whole child. Our approach builds strong academic foundations while encouraging independence, confidence, creativity, and social-emotional growth. Core learning areas for nursery, Pre-K 1, Pre-K 2, and kindergarten include language and early literacy, mathematics, practical life skills, sensorial exploration, cultural studies, science, creative arts, and social development. This integrated program ensures learning is meaningful, engaging, and developmentally appropriate for every child.
