Robyn brings 16 years of Montessori teaching experience, 16 summers of assisting at the Montessori Training Center, and two years as Director of Education with her to lead the Montessori Lab School at Grand Center. Having attending Montessori as a young child, she feels at home and completely fulfilled in Montessori. Robyn and her husband have four sons and two grandsons. While the older sons are alumni of Montessori, the younger two actively attend Montessori Elementary and Montessori Adolescent Programs.
