Biography

Mark Lanier, founder of The Lanier Law Firm, is a nationally recognized trial lawyer known for his accomplishments in complex civil litigation. Based in Houston, Texas, he has spent more than 35 years representing individuals, families, and businesses in cases involving mesothelioma and asbestos exposure, personal injury, pharmaceutical liability, defective medical devices, product liability, and major commercial disputes. His trial work has produced jury verdicts totaling more than $20 billion.

Throughout his career, Lanier has led trial teams in significant litigation, including the $4.69 billion verdict in Ingham v. Johnson & Johnson, subsequently reduced to a $2.1 billion judgment; a $9 billion verdict involving the diabetes medication Actos; and the $253 million verdict in Ernst v. Merck, the first Vioxx trial in the United States. His experience also encompasses major verdicts involving defective DePuy hip implants, national opioid litigation against major pharmacy chains, and a $6 million verdict against Meta and Google's YouTube in the nation's first social media addiction trial.

Lanier is known for making complicated scientific, medical, and technical evidence accessible to juries. His approach combines extensive preparation, compelling storytelling, and carefully developed courtroom presentations to communicate complex legal issues. His litigation work has received national media attention, including coverage in The New York Times, The Wall Street Journal, Bloomberg, and other leading publications.

Among his numerous professional distinctions, Lanier is the only attorney nationwide to have achieved Chambers USA's "Star Individual" ranking in both Product Liability: Plaintiffs and Litigation: Trial Lawyers. He has also been inducted into the Lawdragon Leading Lawyers Hall of Fame and The National Trial Lawyers' Trial Lawyer Hall of Fame and received The National Law Journal's Lifetime Achievement Award.

Lanier also contributes to the development of trial advocacy through legal education. He lectures at prominent law schools, including Harvard and Stanford, and leads the annual Lanier Trial Academy, which brings together more than 1,000 plaintiffs' attorneys to study trial strategies and courtroom techniques.
