She passed the bar examination in 1955, when there were only 11 women on the list of more than 4,000. Von Beroldingen has a successful career as a lawyer before entering politics. She was appointed to the San Francisco Civil Service Commission in the early 1960s, where she contributed to ending discrimination in city hiring and promotion of women and gays.

Originally appointed by MayorJohn Shelley, she was subsequently elected three times; she was the third woman ever to serve as a member of the board and the first woman to chair its Finance and Budget Committee. Von Beroldingen was the first woman appointed to the Board of the Golden Gate Bridge, Highway and Transportation District and was instrumental to the San Francisco Commission on the Status of Woman, an anti-workplace gender discrimination agency. In the early 1970s, Von Beroldingen was "the city's first elected official to envision and actively champion a bold concept for using underdeveloped land in the South of Market area to stimulate local economy, create affordable housing and increase jobs," a vision which later became the Mission Bay project. She left the board to accept an appointment as a judge of the San Francisco Municipal by Governor Jerry Brown. She won elected unopposed three times, then narrowly defeated Nancy Davis with 50.6 percent of the vote in a highly contested election in June 1998.
