Dr. Crosthwaite's advocacy extends to crucial community victories. In 2022, he spearheaded the effort to secure $250 million in state funding for the rebuilding of Lynwood High School's Imperial Campus. His guidance also led to every Lynwood Unified school receiving Positive Behavioral Interventions and Supports (PBIS) awards in 2022, recognizing their outstanding efforts in fostering positive and engaging learning environments for all students.
A proven collaborator, Dr. Crosthwaite is deeply involved in both statewide and national educational initiatives. He is a member of the League of Innovative Schools, the Rise Up Coalition, Edloc, and the National Academy of Sciences and Engineering.

He then transitioned into administration, serving at all levels—elementary, middle, and high school. Academically, he holds an undergraduate degree from UCLA, two master's degrees from California State University, Los Angeles, and Harvard Graduate School of Education, and a Ph.D. in Education from Claremont Graduate University.
Dr. Crosthwaite is married and a proud parent of two college-aged students. One is currently pursuing a bachelor’s degree, and the other is working toward a master’s degree in education.
