From Local Ambition to Global Impact
Born into a working‑class family in Inglewood, California, John Arrillaga was one of five children in a household his father ran a produce market and his mother took in laundry to help support the family. His Basque ancestry (via his father’s lineage) also shaped one strand of his personal story.
