Who We Are

Seels International Montessori School (SIMS) is an international learning community dedicated to nurturing the whole child. Our mission is to help children become confident, capable, and compassionate individuals who can thrive in a global world.

​

Montessori Approach

Our Montessori classrooms encourage independence, concentration, and a love of learning. Children explore carefully prepared environments where they choose activities, develop problem‑solving skills, and grow at their own pace.

​

English Immersion & Jolly Phonics

SIMS provides full English immersion, allowing children to absorb the language naturally through daily interaction. The Jolly Phonics program strengthens early reading and pronunciation skills through fun, multisensory activities.

Eiken Support

SIMS also offers Eiken preparation for elementary students, helping them strengthen vocabulary, reading, listening, and test‑taking skills in a supportive English environment.

​

Two Campuses
