When Marilyn Diaz joined the Pasadena Police Department in 1974, she had to change into her uniform in the bathroom. There was no women’s locker room — because she was the department’s first female patrol officer. In March 2006, she was sworn in as chief of the Sierra Madre Police Department, becoming the first woman to head a city police department in Los Angeles County and one of fewer than a dozen female chiefs of municipal departments in California.
