Sean Morris represents clients in complex commercial litigation, with particular emphasis on mass torts, unfair business practices, and government civil claims. Sean has a proven track record of helping clients navigate high-profile matters and has served as lead defense counsel in several MDL and state Attorney General actions. He is head of the firm's Los Angeles office.
Sean has been at the forefront of defending against public nuisance claims brought by governmental entities against private businesses. Among his significant cases, he successfully tried the California lead pigment litigation, in which public prosecutors asserted that former manufacturers of lead pigment should be held liable for the alleged health hazard created by the existence of lead paint on millions of private residences.
Sean has been named one of the "Top 100 California Lawyers" by the Daily Journal (2019), recognized by The Legal 500 for Product Liability/Mass Tort and IP/Copyright (2011, 2021), and selected as a BTI Client All-Star for Commercial Litigation (2020).
In addition to his commercial matters, Sean maintains a robust pro bono practice, including representing military sexual assault survivors and pursuing impact litigation on behalf of immigrant families who were separated at the border by the U.S. government under its "Zero Tolerance" policy.
