The two wings of this building are home to CA’s Kindergarten through Grade Five classes.
The Gates Family Foundation Wing and the Alger Wing were built and renovated, respectively, in 1998. The wings join at the location of the Lower School Library and the technology I-Lab. The south side of the building features a garden honoring Dr. Tom Fitzgerald, former teacher, principal, and parent, and his wife, Billie Jean. The Alger Wing was named to honor Louisa Alger, a former teacher.
