Zantac Lawsuits | Case Referral

The attorneys of Wisner Baum consider it a privilege and honor to partner with co-counsel to achieve the absolute best results for our clients.

As lawyers reach out to us about case referrals, our Zantac cancer lawyers are eager to establish relationships with law firms and attorneys across the country through case referrals or as co-counsel. We are equipped to litigate thousands of cases.

We were among the first to file personal injury lawsuits in October 2019 against the manufacturers of Zantac, alleging the popular drug contains a cancer-causing chemical at levels up to 3,000 times greater than the Food and Drug Administration’s (FDA) legally allowable daily limit.

Senior shareholder and lead trial attorney, Brent Wisner, directs the Zantac litigation for Wisner Baum. The judge overseeing the Zantac MDL appointed Brent to the Practices and Procedures Team to help establish the protocols and methodology for litigating the tens of thousands of cases to be filed in the years to come. He is one of a select few attorneys to be appointed to the Zantac litigation leadership.

Brent has spoken at many lawyer conferences since October 2019 about the science behind the Zantac cases and the liability of the defendants. He spoke on the Zantac panel at the Mass Torts Made Perfect conference in Las Vegas in October 2019, various Harris Martin Zantac and MDL Conferences in 2019 and 2020, Masters of Mass Tort in Cancun, as well as an AAJ webinar on the topic, the opening MTMP Connect Webinar on Zantac on March 26, 2020 and the MTMP Connect Zantac Census Plus webinar on April 8, 2020.

Brent manages a highly-trained team of attorneys and takes pride in personally working up all aspects of the mass torts he works on, including briefing, expert discovery, and trial and, if needed, appeal.

Your Zantac Case is in Good Hands with Our Firm

Lawyers refer cases to Wisner Baum for a number of reasons. In their own words, they like that we are “a strong group of lawyers” and that we “thoroughly understand the law and fight vigorously for the rights of their injury victims.” Referring and co-counsel lawyers find that we are a “pleasure to work with and bring vast knowledge and experience to every project” and that we are “always on the cutting edge of creative legal theories and exciting cases.”

Whether a firm simply wants to refer their cases or work them up with us, we welcome the opportunity to partner with like-minded lawyers, to hold wrong-doers accountable, and make a huge difference in the lives of our clients.

Michael Baum, Wisner Baum’s senior partner, is both an exemplary attorney and human being. He has flawless integrity, compassion and relentless commitment to the highest ideals. Those qualities have become the aspirational virtues for all the attorneys in the firm. During my many interactions with Wisner Baum lawyers, including multiple visits to their offices, this firm strikes me as an idyllic and joyful place to work. I have watched Michael and his partners during three month long trials and I have partnered with them in other lawsuits. They are all diligent, responsible and gifted attorneys. I want to say a word about one young partner, Brent Wisner. I have watched many of America’s greatest trial lawyers in action, but none better than Brent. Both judges and juries love him for his integrity, his lightening wit, easy humor, buoyant wit and infectious magnetism. His grasp of both science and law is encyclopedic. His greatest gift is his capacity to distill complexities into a simple and compelling cascade of moral outrage. His mesmerizing cross examinations begin as piercing and end in annihilation. Brent is a wrecking ball with charm. It’s no accident that all of the great plaintiff’s firms that are part of the Monsanto Multi-district litigation chose Wisner Baum to try the first three cases. You can’t get a more convincing endorsement than that.

Since 1985, Wisner Baum has obtained more than $4 billion in verdicts and settlements on behalf of clients across all areas of practice, which include cases other firms referred to us. Our firm has worked with hundreds of lawyers and law firms across the U.S. in every area of practice we litigate.

In 2018, The Miller Firm of Orange, Virginia, invited Mr. Wisner to serve as co-lead trial counsel in the first Monsanto Roundup case to go before a jury. The case, Johnson v. Monsanto Co., was the first case of three against Monsanto that Brent and a highly-skilled team of Wisner Baum lawyers, including Michael Baum and Pedram Esfandiary, and staff would help try, along with lawyers and support staff from The Miller Firm.

Brent delivered the opening and closing statements in Johnson, which culminated in a $289.2 million jury verdict.

In 2019, The Miller Firm invited us again to co-try the third Roundup cancer case against Monsanto on behalf of a California couple who alleged exposure to Roundup weed killer caused them to develop non-Hodgkin lymphoma. Brent was honored to deliver the opening and closing statements in this trial as well. The jury trial of Pilliod et al. v. Monsanto Co. culminated in a $2.055 billion verdict for our clients, the eighth-largest personal injury jury verdict in U.S. history, according to CNN.

Andrus Wagstaff and The Moore Law Group invited Brent to join their trial team in the second Roundup trial, representing Edwin Hardeman. Brent presented one of the key fact witnesses for the plaintiff and cross-examined many of the corporate witnesses. The jury rendered an $80 million verdict in favor of the plaintiff.

In the Roundup litigation, our firm holds leadership positions in the federal multidistrict litigation and in cases consolidated in the California JCCP. In the past, members of the firm served on plaintiff steering committees in a wide variety of litigations, from commercial airline disasters to pharmaceutical product defect cases.
