• Mary O'Brien, Head of School

    Mary started Arbor in 1993 to bring Montessori elementary education to the Sammamish Plateau. More selfishly, she founded the school for her three children, the oldest of whom is Mr. Sean, the lower elementary teaching assistant.  Mary was the on-site director of Arbor from its inception through the 2007-2008 school year.  Beginning with the 2008-2009 school year she turned over the day to day operation of the school, but continued to be involved behind the scenes as the owner of the school.  Recently Mary has returned to her former position as  Head of Arbor School.  Her passion for Montessori education still burns strongly and she plans to stay in this position as Head of School for the next several years.
