Kathy Hilton
Kathy Hilton has been with the Sherman Oaks Nursery School program for over fifty years. Her story begins at the Sherman Oaks Presbyterian Nursery School where, armed with her degree in Early Childhood Education, she began student-teaching at the nursery school in 1972 under founding Director Wendy Cummings.
Kathy joined the teaching staff in 1974 and taught in all of the classrooms, for every age level, and in all of the enrichment programs offered. Kathy and her husband Gary became parents along the way to two sons. She has found that the dual role of parent and teacher has been invaluable in her understanding of and caring about all that parents face in raising their children.
