Our History

Welcome to Gilman Montessori Academy! GMA is an early childhood Montessori school with eight years of rich history in the Issaquah and Sammamish communities. Originally founded as a family daycare, GMA soon grew to become Trillium Montessori. Trillium Montessori was the first Montessori bilingual school in Issaquah, with its teaching style famous for its warm environment, family teaching mindset, and rigorous teaching in alignment with the Montessori philosophy. After three years of development, Trillium Montessori School outgrew steadily increasing local demand for admissions. The school developed and relocated to Issaquah and has become Gilman Montessori Academy today!
