Welcome To Sunstone

Throughout its long and rich history, Sunstone Montessori School has provided families with an outstanding educational experience. Ideally located in a beautiful residential neighborhood, we are ten minutes from downtown Portland, and two blocks from the Willamette River Greenway, home to purple martins and great blue herons. Our school is housed in the historic Terwilliger School building with a spacious campus featuring outdoor learning environments, a variety of ecological gardens, playgrounds, and a soccer field. Sunstone serves children from 16 months to 12 years of age, and is proud to have achieved the highest accreditation, Recognized School, by the Association Montessori Internationale – AMI/USA.
