Our attorneys also serve clients in Iowa, Missouri, Nebraska, New Hampshire, and Wisconsin.

We have handled some of the most contentious cases that have helped define insurance defense litigation and have earned a reputation for targeting the threat of and stopping Nuclear Verdicts® – runaway jury verdicts exceeding $10 million.

Our trial-only subsidiary, TM HALO®, is wholly dedicated to stemming the tide of Nuclear Verdicts®. Comprised of elite Tyson & Mendes defense attorneys with decades of courtroom experience, TM HALO® lawyers parachute in to manage the thorniest, highest-stakes cases.

We ensure our attorneys have the tools to achieve exceptional results and protect clients from excessive jury awards. Through programs like TM University and the Tyson & Mendes Trial Academy, our attorneys receive deep training on proven defense methods outlined in Founding Partner Robert Tyson’s best-selling book, "Nuclear Verdicts®: Defending Justice for All."

Our newest strategy, The Apex, builds on 20+ years of courtroom success and data from 100 Nuclear Verdicts®. Launched in 2025, it is a trial-proven framework to help defense teams recognize and break patterns in high-stakes litigation. The strategy is detailed in our forthcoming book, "Nuclear Verdicts®: The Apex – Break the Pattern," by Founding Partner Robert Tyson and National Managing Partner Cayce Lynch.
