Sonia Chang-Díaz is a former public school teacher and the first Latina and Asian-American to serve in the Massachusetts State Senate — and she’s spent her career fighting for and winning the bold change that working families need. Sonia’s mom was a social worker. Her dad came to America with $50 in his pocket and became NASA’s first Latino astronaut. Now she’s building a movement to tackle our state’s biggest challenges and restore Massachusetts’ promise to all families.
