John Gsanger occupies a niche few injury lawyers can claim: the Texas Board of Legal Specialization has awarded him a rare double Board Certification, covering both Personal Injury Trial Law and appellate work. For a victim weighing Houston lawyers, that means the same attorney who tries the case can also defend the verdict when a corporation appeals — a combination that has repeatedly proven decisive in his multimillion-dollar wins against major tire and automobile manufacturers.
Gsanger’s career has been defined by product safety. His nationwide practice at The Ammons Law Firm has produced settlements that triggered recalls of defective tires and dangerous sport utility vehicles and pushed manufacturers to disclose critical safety warnings to consumers — outcomes that protect future drivers, not just his own clients. Among his listed results is a $33 million recovery in a tire defect case arising from a 2013 head-on collision that took the life of a beloved community leader.
He is also one of the profession’s teachers. Gsanger serves as a contributing author for the Texas Pattern Jury Charge Committee — the body whose work shapes how Texas juries are instructed — and has been invited to teach at more than 100 continuing legal education seminars from coast to coast. His publications include The Ultimate Book on Advanced Trucking Litigation (2017), a 2016 guide to spotting seatbelt and tire defect cases hidden inside ordinary car crash claims, and 2015 work on road construction defect litigation. Texas Monthly’s Super Lawyers list included him every year from 2009 through 2019, and the Corpus Christi Association of Legal Professionals once named him Boss of the Year.
His academic record set the stage early. Gsanger earned a Bachelor of Arts with Special Honors in the Plan II program at the University of Texas at Austin in 1987, then completed his Juris Doctor on scholarship at the University of Texas School of Law in 1991, where he was Editor in Chief of The Review of Litigation, an editor for the American Law Institute’s Symposium on Complex Litigation, and president of the University Civil Liberties Union. He followed with postgraduate comparative law studies at Queen Mary and Westfield College, University of London, in 1992. He is admitted in all four federal district courts in Texas and belongs to the College of the State Bar of Texas.
Gsanger is the attorney to call when a crash may involve more than driver error — a tire that failed, a vehicle that rolled over, a seatbelt that did not hold, a commercial truck, or a hazardous road construction zone. These cases demand engineering-level investigation and the resources to fight manufacturers, and they are precisely what he has built his career on. The firm offers free consultations and takes cases on contingency, with no fee unless there is a recovery.
