Bob introduces himself as a “family lawyer.” Since 1975 he has had offices in San Francisco and has represented families who have lost their bread winner to a catastrophic or fatal injury. To Bob, “family lawyer” does not mean a lawyer who represents a husband or wife going though a divorce. Rather, a “family lawyer” is a lawyer who has the grave responsibility of regaining the family dignity that existed before the tragedy and giving the family their economic freedom.

For the last 38 years, Bob has prosecuted personal injury and class action cases. His practice has ranged from cases involving banking issues, online rights of privacy, employment cases, various consumer goods and services, skilled nursing care, and various other fields. Bob is inspired and gratified by representing all his client, from construction workers, to classes of consumers, to top executives at Fortune 100 corporations.

In 2003, Bob fulfilled a dream when he purchased the building at 515 Folsom Street in San Francisco and opened a new space, designed solely for the efficient representation of those in grave need of legal help. The Arns Law Firm physical plant is built to mock try cases to jury panels, which are videotaped and viewable through a one way mirror.

As a trial lawyer Bob is most fulfilled by being surrounded by his incredible clients who represent the highest work ethic in our country and who make up impressive families. Further, Bob is always amazed at the commitment of the legal assistants and lawyers in his office. Every lawyer in Bob’s office has obtained numerous seven figure and eight figure verdicts and has the heart to fight relentlessly for families in need. Bob’s dream – his experiment – in forming The Arns Law Firm is now being fulfilled beyond his expectations.
