The Old Adobe School is a private preschool housed on the grounds of Sonoma's First Congressional Church. This nonprofit secular school, founded by board member John Larson, enrolls children who are between the ages of 2 and 5, and has an after-school child-care program. The school has a creative, hands-on curriculum, in which children engage in activities to learn concrete skills. As the website states, "You may find children making a number chart out of the fruit they brought for lunch, cutting plants for flower arrangements or creating bubbles to study the properties of water."
