Brookside School is one of three elementary schools in the Ross Valley School District. The school is divided into two campuses. The Lower Campus serves predominantly grades K-2, though some second grade classrooms have been moved to the Upper Campus. In the 2011-12 school year, the two Brookside campuses (which are separated by nearly a mile) will become two separate schools. The Lower Campus is overseen by Principal Marci Trahan, and serves the communities of Sleepy Hollow and the San Anselmo-Fairfax border.
