Our Successes

Wisner Baum: Top Rated Lawyers Reaching the Heights of Professional Excellence

Wisner Baum is a national award-winning law firm that has obtained some of the largest settlements and verdicts in recent history. Our team has successfully represented thousands of clients across the United States and abroad in personal injury and wrongful death lawsuits, class actions, whistleblower claims and more. We have decades of experience taking on negligent corporations and entities to hold them accountable for the harm they have caused.

The legal industry has recognized Wisner Baum with prestigious awards, including Law360’s Regional Powerhouse award and Product Liability Practice Group of the Year. The National Law Journal has twice awarded them with Elite Trial Lawyers Trial Team of the Year and inducted them into the Verdicts Hall of Fame. Wisner Baum is also listed in U.S. News – Best Lawyers® “Best Law Firms” and has maintained an AV® preeminent peer-review rating by Martindale-Hubbell for decades

With more than $4 billion in verdicts and settlements we take pride in our approach to litigating cases and doing what is needed to get the best resolution possible for our clients. Collectively, our attorneys have conducted trials in more than 200 cases, including aviation disasters, truck accidents, pharmaceutical drug injuries, and product liability. 

With experience, skill, the resources and relentless dedication, we commit to overcome and resolve some of the greatest challenges on behalf of consumers and injury victims, both in our home state of California, nationwide, and even internationally.

While the majority of cases involving complex litigation—from commercial transportation cases to drug product liability cases—will settle before a trial is ever conducted, our attorneys at Wisner Baum always prepare each one of our cases as if it were going to trial.

Some clients prefer to have their case resolved before trial, while others desire to see their case result in a trial. Regardless of the final outcome, we feel that preparing each case as if it were going to trial has a significant impact on the behavior of the defendants in settlement negotiations and in the courtroom.

We also strive to find ways, using our history of success, to shine the spotlight on important issues that affect consumers and to improve the safety of the unsafe products or harmful practices which brought about the litigation in the first place. Our safety advocacy campaigns have helped improve transportation, medication and consumer products affecting the public at large.
