Martini is part of a large extended Italian-American family, some of which reach back four generations in California.
Steve Martini was born on February 28, 1946, in San Francisco, and grew up in the Bay Area and Southern California. Martini’s parents moved to Los Angeles County, California in 1956. His father, Ernest Martini, was a rancher, managing and owning farms throughout California during his lifetime. His mother, Rita, was a housewife and homemaker, though in later years she worked extensively in the local library in San Gabriel, California.
