Pedram Esfandiary is a partner and trial attorney based in the Los Angeles office of Wisner Baum, where he concentrates his practice on toxic tort injuries, pharmaceutical drug liability, class actions, consumer fraud litigation and police misconduct lawsuits. He was promoted to partner in March 2023. He is the youngest lawyer to earn this distinction at the firm.

He is currently leading the firm’s legal team handling the toxic baby food litigation. This new mass tort litigation involves allegations against the major brand manufacturers (Nurture Happy Family Organics, Beech-Nut, Hain, Plum Organics, Walmart-Parent’s Choice, Sprout Foods and Gerber) for knowingly selling baby food with “dangerously high levels” of toxic heavy metals. Baby food contains dangerous levels of arsenic, cadmium, lead and mercury, toxic heavy metals known to damage neurological development and brain development and associated with autism and ADHD in children. In 2023, The Recorder|ALM| recognized Pedram as a winner of their California Legal Awards in the category of Lawyers on the Fast Track (under 40) for his track record of success.


As the number of children diagnosed with autism hits staggering highs, a groundbreaking lawsuit against the top baby food manufacturers seeks to show toxic metals in baby food can cause autism. Spotlight on America interviewed Wisner Baum lawyer Pedram Esfandiary and our client Melissa Cantabrana. Watch it here.

Pedram Esfandiary Attorney, Partner

Locally & Nationally Recognized

Pedram recently successfully sued the Burbank Police Department (California) for police misconduct, civil rights violations, assault, battery, unlawful seizure, excessive force and negligence. He also obtained a settlement from the City of Irvine when its former mayor violated one of its citizen’s first amendment rights when she blocked him from posting to her personal Facebook page which she was using as a public forum concerning official mayoral business.

He was an integral part of the trial team that won the historic $2 billion verdict against Monsanto (now Bayer) in May 2019 on behalf of a couple who together sprayed Roundup weed killer on their properties for 30 years. The jury in Pilliod, et al. v. Monsanto determined that Roundup exposure caused Alva and Alberta Pilliod’s non-Hodgkin lymphoma, and that Monsanto failed to warn the couple about the cancer risk associated with Roundup use. The jury awarded them $55 million in compensatory damages and $2 billion in punitive damages.

He also served in a similar capacity on the very first Roundup cancer case to go to trial against Monsanto, resulting in a $289 million verdict on behalf of groundskeeper Dewayne “Lee” Johnson. In addition, he participated in the second Roundup trial against Monsanto on behalf of Edwin Hardeman. The jury in that trial awarded Mr. Hardeman $80 million for his damages.

In recognition of his work in the Monsanto Roundup trials, Pedram has received well-deserved awards. He was selected as a winner on Law360’s Rising Stars Top 40 Under 40 list for 2019, which recognizes attorneys whose legal accomplishments transcend their age. Pedram has also been selected to Southern California Super Lawyers® – Rising Stars and the National Trial Lawyers Top 40 Under 40.

He and other members of the Roundup trial teams in Pilliod, Hardeman and Johnson were also honored as Elite Trial Lawyers Mass Tort Law Firm of the Year finalists in 2020 by ALM and the National Law Journal, as well as the 2019 Trial Team of the Year 2019 by the National Trial Lawyers Top 100. At the end of 2020, the National Law Journal inducted Pedram and his colleagues into The Verdicts Hall of Fame and Law360 named them Product Liability Practice Group of the Year.

Various legal journals have top listed our landmark Roundup verdicts. The Daily Journal listed the $289M Johnson verdict among its top verdicts of 2018, the National Law Journal listed it in their Top 100 and Courtroom View Network listed it in its Top 10 Most Impressive Plaintiff Verdicts of 2018. listed the $2B Pilliod verdict as #1 in California, #2 in the nation and the ninth largest verdict in history in 2019. The National Law Journal and the Daily Journal also recognized the Pilliod verdict in their top lists.

After the Johnson v. Monsanto verdict, UCLA School of Law, Emmett Institute on Climate Change & the Environment, and The Resnick Center for Food Law & Policy, as well as Yale Law School’s Collaboration for Research Integrity and Transparency (CRIT) program, invited Pedram to speak about how the trial team won the verdict and what it means for the legal community and the environment.
