Chamber Chat: Episode 3 – Meet Arbor Montessori

Arbor Montessori was founded in 1993 by Mary O’Brien with a clear and enduring purpose: to educate each child as a whole, unique person. What began with just eight elementary students on two acres of farmland on the Sammamish Plateau quickly grew into a thriving Montessori community rooted in respect, compassion, and authentic Montessori practice. From the beginning, Arbor has been family-owned and guided by the belief that children learn best in a peaceful, inclusive environment that honors curiosity, independence, collaboration, and a deep love of learning.
