Robert Arns is the founder of Arns Davis Law. Throughout his distinguished career, Bob has exclusively prosecuted plaintiff cases, ranging from consumer class actions to individual cases involving catastrophic injuries and death.

Throughout his distinguished career, Bob has exclusively prosecuted plaintiff cases in various areas of law. His expertise extends to consumer class actions, such as wage and hour disputes, independent contractor misclassification, banking, privacy, and other instances where consumers have been wronged by companies. He has also represented families in individual cases involving catastrophic injuries, death, and other significant matters. His practice encompasses on-the-job injuries, including construction site incidents, catastrophic automobile accidents, defective product cases, electrocution, unsafe premises conditions, equipment failure, elder abuse, and sexual assault and abuse.

Bob takes pride in calling himself a “family lawyer” and has represented families across the United States in class actions or cases where a breadwinner or loved one has suffered a tragic death or catastrophic injury. To Bob, being a “family lawyer” means taking on the solemn responsibility of restoring the family’s dignity that existed before the tragedy and helping them regain their financial independence.

In addition to his legal practice, Bob has been teaching Civil Trial Practice at the University of San Francisco Law School for almost 20 years, sharing his extensive knowledge and experience with future generations of attorneys. He also serves on the board of Bay Area Legal Aid, further demonstrating his commitment to justice and advocacy.


Bob has an exceptional legal career, securing over $1 billion in paid results for plaintiffs through trials and settlements. He is a recipient of the San Francisco Trial Lawyer Association’s Trial Lawyer of the Year award and has been a finalist for The Consumer Attorneys of California Trial Lawyer of the Year multiple times.

For 18 years, Bob taught trial practice as an adjunct professor at the University of San Francisco School of Law, receiving the Professor of the Year award in 2010. He graduated from USF School of Law in 1975 with a full scholarship and ranked in the top 5% of his class. Prior to that, he graduated summa cum laude from UC Santa Barbara in 1971.

Bob is the author of the best-selling Rutter Group publications The Evidence Wheel and The Trial Wheel, used by trial lawyers and judges across the United States. He has presented at numerous ABOTA Masters of Trial events and seminars on trial practice and evidence.

Throughout his career, Bob has represented diverse clients, providing them with economic security. He owns Arns Davis Law buildings in San Francisco and Reno, with the San Francisco office featuring a state-of-the-art mock trial facility.

He also has various real estate ventures, including the Arns Davis Law building in San Francisco, Baranof Wilderness Fly Fishing Lodge in Alaska, and several residential and commercial properties.

Bob is an avid fitness enthusiast and enjoys golf, cycling, fly fishing, and outdoor activities. He cherishes spending time with his family and friends and is committed to giving back to the community through philanthropy in various areas such as academics, athletics, legal aid, food banks, and other community-enrichment initiatives.

Bob credits the balance in his life to the unwavering support of his wife, Anne, his children, their spouses, and his five amazing grandchildren, as well as the outstanding team of lawyers and legal assistants at Arns Davis Law.
