10/10GreatSchools RatingParent Rating AverageI wish I could write a five star review. I would only give credit to those hard-working teachers unfortunately our experience at the school has not been very positive. There is a huge problem with bullies at the school and I feel like there isn’t anything being done about it if a child has a special need and requires a combination the school will deny an aide for your childParent Review3mo ago - Park Elementary School

10/10GreatSchools RatingParent Rating AverageI bought my home in 1993 in Mill Valley because I Heard that the Public schools in Mill Valley were fabulous. I am a single mother and have raised two beautiful daughters in this community. We chose Park school mainly because it was closest to our house however, I have to say that it was a phenomenal choice!I have nothing but fantastic things to say about the teachers and their devotion to the job! My children are both grown now and found their ways into their dream colleges. Bravo! Park Scool!!Parent Review9y ago - Tamalpais Valley Elementary School

10/10GreatSchools RatingParent Rating AverageWe have had kids at Edna for 9 years. It is a warm, loving place with a very engaged parent community. Kids have access during the schooldays to art, outdoor education, music, and much more. There are tons of extracurricular activities available on campus after school, which is a really lovely addition to the school experience. The administration is responsive and caring.Parent Review1y ago - Tamalpais High School
