In Marin County, California, nestled in the trees of Ross Valley in the lovely town of San Anselmo, lies a special place where families come to share in their preschoolers first learning experience. Since 1947, San Anselmo Cooperative Nursery School has continued to provide a supportive environment where children make choices, practice social skills and play freely with numerous friends (many of whom become friends for life). It is our hope that young children and their families look back on their time here as one of the most rewarding experiences of their lives.
