R. Brent Wisner is an attorney and senior shareholder in the San Francisco Bay Area office of Baum Hedlund Aristei & Goldman. Brent is driven by a deep-rooted passion for using the law to help those 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, and consumer fraud litigation. In 2022, Brent was selected to become an Associate Fellow of the Litigation Counsel of America (LCA) trial lawyer honorary society. LCA Fellows are selected after being evaluated for effectiveness and accomplishment in litigation, trial work, and ethical reputation.

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. He takes pride in personally working up all facets of litigation—from briefing, expert discovery, through trial and, if needed, appeal. After obtaining two landmark verdicts against Monsanto, he has been showered with major awards and recognition. He is the youngest attorney in U.S. history to win a multi-billion-dollar jury verdict. Brent has achieved multiple verdicts totaling $2.427 billion, and negotiated mass tort settlements in excess of $1 billion.
