Welcome to Sammamish Montessori School (SMS)
For the past 48 years, our unique approach to early childhood education—blending authentic Montessori philosophy with enriching programs such as STEAM, outdoor learning, and community events—has laid the educational foundation for more than 5,000 students. Located in the heart of Redmond, our school is re-accredited by the American Montessori Society (AMS) through 2032, a distinction held by only 10 schools in Washington State — and approved by the Washington State Board of Education (SBE).
We serve children from 18 months (Toddler) through 9 years old (Lower Elementary), and we are proud to have 25+ AMS-accredited Montessori teachers along with more than 30 assistants, administrative team members, and support specialists in Music, Art, Spanish, and Physical Education — ensuring a rich, well-rounded learning experience for every child. With over 24,000 sq. ft. of dedicated playground and outdoor learning space, our students enjoy daily opportunities for movement, exploration, and active, hands-on learning.
Over 250 families rely on us each year for their child’s early education and care, trusting our commitment to exceptional Montessori learning and whole-child development.
