R. Brent Wisner became the managing partner of Wisner Baum (formerly Baum Hedlund Aristei & Goldman) in early 2023 at the age of 39. He is driven by a deep-rooted passion for using the law to help those who have been marginalized and hurt by large, and sometimes malicious, corporations. He is honored to lead the firm into its next chapter and continue the legacy of his predecessors.
Brent has litigated cases against such companies as Bayer, Eli Lilly, Forest Labs, GlaxoSmithKline (GSK), Monsanto, Pfizer, Sanofi and Takeda and obtained multiple verdicts totaling $2.427 billion and negotiated mass tort settlements in excess of $1 billion, all before the age of 40. He is the youngest attorney in U.S. history to win a multi-billion-dollar jury verdict, which he achieved in 2019 with a $2 billion Roundup cancer verdict against Monsanto on behalf of the Pilliods.
His firm is leading several litigations that will see their first trials in 2023 and 2024. These include the Zantac cancer litigation in California, in which he serves as co-lead counsel for the Ranitidine Product Cases JCCP 5150. His firm will also try the first of its kind toxic baby food lawsuit in California in 2023 and the first Gardasil HPV vaccine injury lawsuit against Merck in 2024.
Brent’s age belies an incredible track record of success in major cases which many legal publications have recognized. He has received numerous awards, such as “Civil Plaintiffs Trial Lawyer of the Year” by ALM and National Trial Lawyers and has been named one of “America’s 50 Most Influential Trial Lawyers” and earned “Elite Trial Lawyers” recognition from 2018 to 2020 by The National Law Journal. Law360 recognized Brent as a “Titan of the Plaintiffs Bar” and, in 2020, awarded Brent “MVP of the Year” in Products Liability. In 2021, Brent was awarded “West Trailblazer” by The American Lawyer and the “Clarence Darrow Award” by Mike Papantonio, founder of Mass Torts Made Perfect. Brent is consistently recognized in the Daily Journal’s “Top Plaintiffs Lawyers” and “Top 100 Lawyers” in California. He is also inducted in the Verdicts Hall of Fame by the National Law Journal and Verdict Search and is listed in Best Lawyers in America® and Lawdragon 500 Leading Plaintiff Consumer Lawyers.
