Austin Moore litigates high-stakes cases. He practices in state and federal courts across the country and regularly takes on major corporations in nationwide class actions. Austin has been recognized as one of the “Top Attorneys Under 40” in the country by Law360, named a “Rising Star” in class action law by Super Lawyers, and honored as an “Up and Coming Lawyer” by Missouri Lawyers Weekly.

Austin focuses his practice on three primary practice areas:

Data Breach and Privacy Litigation. Austin is a national leader in data breach and privacy cases. He has played key roles representing consumers in many of the nation’s largest data breach class actions, including lawsuits against T-Mobile, Target, the Home Depot, Anthem Insurance, Equifax, and Marriott. Austin’s recent successes include:

Austin has served as appellate counsel in multiple precedent-setting data breach cases addressing Article III injury and is currently serving as President of the Data Breach and Privacy section of the American Association for Justice.

Consumer Class Actions. Austin represents consumers who have been harmed by corporate misconduct, including false advertising, deceptive practices, and credit reporting errors. Austin recently obtained one of the largest recoveries in history relating to inaccurate credit reports, securing $29 million in settlements in two pioneering cases against Experian arising out of the agency’s reporting of delinquent loan accounts. Austin is currently representing travel nurses and other healthcare workers who were subject to “take-it-or-leave-it” pay-rate reductions in the middle of their contracts

Sexual Abuse Liability. Austin advocates for victims of sexual abuse in civil cases against their perpetrators and other negligent parties. He respects the sensitivity of these cases by working with local counseling centers and adopting a trauma-informed approach to his legal representation. Austin’s recent results include:

  • $8.2 million verdict for sexual assault victim who sued assailant for civil assault and battery
  • $1.5 million settlement in nursing home resident sexual assault case
  • Confidential settlement reached against ridesharing giant Uber after female rider was sexually assaulted by driver with criminal background

Before joining Stueve Siegel Hanson in 2013, Austin was in private practice in St. Louis, where he primarily defended class action cases. He credits this experience with helping him understand how defense lawyers will approach a case – and helping him craft litigation strategies that secure a courtroom advantage.
