In 2019, our firm and co-counsel won a historic $2 billion Roundup verdict against Monsanto (now Bayer), the ninth-largest personal injury jury verdict in United States history and the largest jury verdict in the state of California in 2019.
Our personal injury attorneys represented Alberta and Alva Pilliod, a couple who sprayed Monsanto’s Roundup weed killer for 30 years on their properties. The jury determined that Roundup exposure caused the couple to develop non-Hodgkin lymphoma and that Monsanto failed to warn of the cancer risk. This was the third successful verdict against Monsanto concerning Roundup. Our firm served on the trial team in all three of the first Monsanto trials, and the firm’s vice president, R. Brent Wisner, served as co-lead trial counsel in all but one of the first three trials.
In recognition of the verdict in Pilliod et al. v. Monsanto Co., R. Brent Wisner, co-lead trial counsel for the Pilliods, was awarded 2019 Civil Plaintiff Trial Lawyer of the Year by the National Trial Lawyers and ALM, and listed in the Top 40 Under 40 Attorneys in California by the Daily Journal, Winning Litigators by The National Law Journal and America’s 50 Most Influential Trial Lawyers by Trial Magazine and The National Law Journal. Our firm was also a finalist in 2019 for Elite Trial Lawyers Mass Torts Law Firm of the Year for the third year in a row.
In 2018, our firm and co-counsel won a $289 million verdict against Monsanto on behalf of Dewayne “Lee” Johnson. In recognition of our work, the National Trial Lawyers Top 100 awarded our trial team and co-counsel with “2019 Trial Team of the Year.” Additionally, The National Law Journal and Trial Lawyer Magazine named trial attorney R. Brent Wisner, co-lead trial counsel on the Johnson case, one of “America’s Most Influential Trial Lawyers” and the Daily Journal recognized Brent in the “Daily Journal Top 100 Lawyers for 2018.”
The National Law Journal and ALM Media also awarded our firm two years in a row with the distinguished honor of “Elite Trial Lawyers” first place winner for Pharmaceutical Litigation based on our firm’s work in a high-profile generic Paxil suicide case against drug manufacturer GlaxoSmithKline. The jury verdict in the case of Dolin v. GlaxoSmithKline earned our firm top verdict recognition for the state of Illinois and the nation for 2017.
