It is with heavy hearts that we tell you that our Founder--Mrs. Madeleine Justus--passed away at the age of 99½. She embodied the Montessori spirit. She founded our school in 1951, and helped found organizations like Pacific Northwest Montessori Association, and WFIS where schools come together to help each other.

Our school and her family will miss her dearly.
