Firm Details

The award-winning plaintiff attorneys at Wisner Baum (formerly Baum Hedlund Aristei & Goldman) have earned a reputation for breaking new ground, holding Fortune 500 companies accountable, influencing public policy, raising public awareness, and improving product safety. They have won more than $4 billion in verdicts and settlement for their clients.

Wisner Baum is recognized as a preeminent plaintiff firm that has represented thousands of victims across the nation in aviation, bus, train, and trucking accidents, as well as those harmed by defective pharmaceuticals, medical devices and other consumer products. The firm also represents whistleblowers and litigates class actions.

The firm won the largest verdict in California and the second largest in America in 2019. The Pilliod verdict is also the ninth largest verdict in U.S. history. A team of Wisner Baum lawyers with Brent Wisner serving as co-lead trial counsel, tried the first and third of the first three Roundup cancer cases against agrochemical giant Monsanto Company (now Bayer) that resulted in two of the largest jury verdicts in recent history, worth a combined $2.344 billion. They also assisted with the second trial (Hardeman v. Monsanto Co.). The $289 million verdict in Johnson v. Monsanto Co. and the $2 billion verdict* in Pilliod et al. v. Monsanto Co. were hard-fought legal victories that will have a lasting impact not just for the plaintiffs and their families, but for public health and the environment.

Wisner Baum also represents thousands of children diagnosed with autism spectrum disorder and/or ADHD after being exposed to dangerously high levels of heavy metals in baby foods. Managing partner R. Brent Wisner was appointed co-lead trial counsel in the toxic baby food MDL (multidistrict litigation), overseeing the Plaintiffs’ Steering Committee (PSC). As co-lead trial counsel in other consumer product cases, Wisner has earned over $2.3 billion in combined jury verdicts. Partner Monique Alarcon was appointed Plaintiffs’ Liaison Counsel and Partner Pedram Esfandiary was appointed a member of the PSC.

The firm has successfully litigated against some of the largest corporations in the world, including major airlines, rail organizations, pharmaceutical and medical device companies, agrochemical corporations, and even the federal government.
