Her retirement was announced in a Jan. 29 email to staff and parents from school President John Earnhardt.
"Lisa's true joy comes from visiting classrooms and seeing our students 'in action,'" Earnhardt said. "In her 32 years in education, Lisa has taught at most grade levels of elementary school and knows that the decisions she makes every day impact our children. She is a strong academic leader and that is why she was hired."
Cesario informed the school board about her retirement on Jan. 16. She announced the news to staff and teachers on Jan. 25.
She joined the district, which includes Las Lomitas School (K-3) in Atherton and La Entrada (4-8) in Menlo Park, as superintendent in July 2012. Eric Hartwig preceded Cesario as superintendent, serving from 2007 to 2012. He planned to retire, but ended up taking a role as Portola Valley School District's interim superintendent. He is leaving that position this June.
Before her job at Las Lomitas, Cesario served as assistant superintendent of educational services in the Santa Clara Unified School District for six years. Before that, she was the district's director of educational services.
Earlier in her career she taught third-, fifth-, and sixth-grade students, and was an elementary school principal for six years. She also served a three-year stint as a K-12 coordinator of curriculum and instruction.
The school board plans to hire a search firm and hopes to have a new superintendent begin work on July 1, Earnhardt said. There will be an opportunity for staff, parents and the community to provide input about what they want in a new superintendent, he said.
