Mt. Si Arbor

Welcome to Arbor School's North Bend Campus!

A little bit of our history...

Mary O’Brien established Arbor Montessori Schools on the Sammamish Plateau in 1993. It serves 150 children from infancy through 6th grade. In 2008, the principle of Issaquah Montessori school approached the owner of Arbor hoping that Arbor would keep her dream alive since she was relocating to Eastern Washington. The O’Briens did take on Issaquah Montessori in 2009 and it now serves 90 children from ages 15 months to six years. For several years Arbor Montessori Schools has been looking to join the Snoqualmie Valley Community. In June of 2018 when the owner and operator of Mountain Valley Montessori School found her family relocating to Tacoma, Arbor once more was faced with the opportunity to bring its institutional experience and passion for Montessori to keep another founder’s dream alive. The principles of Arbor have taken over the operations of Mountain Valley Montessori at 248 Main St, in beautiful downtown North Bend. The  school is now operating as Mt. Si Arbor Montessori and serves children from 15 months to 6 years of age for North Bend and Snoqualmie Valley residents.

When you schedule your tour, you will be able to see the many upgrades to the inside and outside of the facility that were done shortly after the purchase in 2018. With new paint, a larger more open classroom environment, brand new floors throughout and an expanded park-like playground this facility is the perfect place to foster a life long love of learning.
