Action Day Primary Plus Lincoln campus for children ages: birth - 5 years includes an Infant Center, Preschool & Jr. Kindergarten. Our Lincoln Avenue campus, located in the heart of Willow Glen, was the third preschool to join the Action Day Nursery Group in 1975. It includes an infant center and preschool housed in three large buildings, the oldest of which was originally a farmhouse that is listed in the Willow Glen guide to historical landmarks. Enrollment is open for children three months to seven years old.
