Kate Hersh-Boyle

I graduated from law school in 2011 and began working at Hersh & Hersh that same year. I have worked on a variety of personal injury matters: medical malpractice involving death and injury, including birth injury, stroke, failed surgery, dangerous and defective drug and device, automobile, pedestrian, bicycle accidents, and business litigation. I have handled all parts of a case from before it is filed through trial.

I am passionate about fighting for justice, winning, and achieving great results for my clients. I had the honor of growing up watching my family, full of incredible lawyers, work passionately to achieve justice and social change by advocating for and helping people who had been injured. I was inspired to do the same. I have the additional privilege of working with my mother, Nancy, learning from her incredible experience and sharing her unwavering passion for justice, the law, and our work.

Besides successfully representing people through trial and settlements, one of the things I have valued most is being able to use skill, intellect, and perseverance to change the law or practices of a provider, entity or industry. I was part of a team that won an appeal in the First District Court of Appeal. The case involved permanent injuries, including blindness and burn-like rashes, sustained by our client from taking a dangerous drug that came without warnings about its risks. The team of Hersh & Hersh lawyers on the case uncovered that the warnings were intentionally omitted from the patient handout pursuant to an agreement between two entities. Hersh & Hersh sued the software provider that distributed the information and altered the software to exclude the warnings. The software vendor filed an anti-SLAPP Motion claiming it owed no duty to our injured client. Our team prevailed in briefing and argument at the trial court level when the Defendant’s anti-SLAPP motion was denied. The Defendant appealed the denial, and I, along with a team of attorneys, won on appeal, resulting in a published opinion, Hardin v. PDX, Inc. (2014) 227 Cal.App.4th 159, that changed the face of the law.

I was born and raised in San Francisco, but I now live in Marin County with my husband, our 3 young daughters and our dog, Lou. We are lucky to have our family in the area and love spending time with family and close friends. I also enjoy traveling, allowing my kids to experience new places and things. I love skiing and am an avid runner and can be found most weekends running or walking one of the many scenic trails of Marin with my family.
