Mass tort claims and catastrophic loss often result in bet-the-company litigation and threaten to disrupt business operations on a large scale. In such critical moments, business continuity is of the utmost importance.

For more than 100 years, Armstrong Teasdale’s trial lawyers have enjoyed unparalleled success in both state and federal courts and have prevailed on a variety of tort and catastrophic loss claims. While we aim for quick resolution, our lawyers also have a reputation for handling high-stakes, high-value matters for clients in the courtroom and have generated more than 30 top-ranking plaintiff and defense verdicts in Missouri alone in recent years.

The firm’s talented team of trial lawyers serves clients on a national level and includes a fellow of the American College of Trial Lawyers, former RNs and medical staff, fire and explosion professionals, former judges and federal investigators. We have decades of combined experience handling matters for clients across the country and across industries related to personal injury, insurance coverage, product liability, medical malpractice, privacy and data security, professional malpractice, vehicular liability and premises liability, among others.
