A 400-year-old live oak tree shades the entrance gate to Casa Montessori. Another covers the back decks and patios, areas for work and play. Our resident squirrel, Frisky Whisk, jumps from limb to limb, roof to roof, entertaining the children with his agility. Native plants and a running track encircle the shaded play area; small garden plots have seasonal flowers and vegetables for each class to tend.
