R. Brent Wisner

Brent Wisner is an attorney and partner in the Los Angeles office of Baum, Hedlund, Aristei & Goldman, PC. A Los Angeles native, Brent is driven by a deep-rooted passion for using the law to helpthose who have been marginalized and hurt by large, and sometimes malicious, corporations.

Brent has dedicated his practice to vindicating his client’s rights and holding wrongdoers accountable. He concentrates his practice on pharmaceutical class action litigation, toxic-tort injuries, whistleblower and qui tam claims, and consumer fraud litigation. Brent also oversees the firm’s Medicare Secondary Payer cases, representing Medicare providers who have lost taxpayer funds to pharmaceutical companies and other large defendants.

Brent is one of Baum Hedlund’s lead trial attorneys and manages a highly-trained team of attorneys on all aspects of the cases in his department. Brent takes pride in personally working up all facets of litigation—from briefing, expert discovery, through trial and, if needed, appeal. Brent is routinely asked to provide commentary and advice to media and other counsel on high-profile cases.

Law360 named Mr. Wisner a “Titan of the Plaintiffs Bar” for, in part, his role as co-lead counsel in a complex trial that resulted in the first multi-million-dollar jury verdict against a brand-name drug-maker liable for injuries caused by a generic version of the drug. The case has been described as groundbreaking and likely to shape the landscape of pharmaceutical litigation for years to come.

Prior to working at Baum Hedlund, Brent served as a Law Clerk for the Honorable Helen Gillmor in the U.S. District Court for the District of Hawaii for two years. While clerking, he worked on several jury trials, both criminal and civil, and was responsible for aiding the Court in resolving complex pretrial and post-trial motions. In addition, he worked on several cases in other jurisdictions, including the District of Arizona and the Eastern District of California. While clerking, Brent also gained valuable appellate court experience when Judge Gillmor sat on the United States Court of Appeals for the Ninth Circuit in Pasadena, California.

Brent received his law degree (J.D.) and a Master of Public Policy (M.P.P.) from Georgetown University prior to his clerkship. While at Georgetown on a scholarship, he was recognized for his commitment to public interest law and received a pro bono service award for completing over 750 hours of volunteer legal work.
