The case involved emergency room malpractice which carried the heightened standard of proof of “willful and wanton” negligence—an incredibly difficult burden to meet. It was the second largest medical malpractice verdict in Texas for 2022. In 2023, Lyons was part of a trial team that obtained an $860M verdict against the multifamily development company Greystar in Dallas County stemming from the collapse of a tower crane that hit an apartment complex, tragically killing a young woman. The verdict was the sixth largest in the entire country for 2023 and the second largest in Texas. In 2024, Lyons was co-counsel in a transportation related wrongful death case against Oncor Energy that claimed the life of a California man who was a professional truck driver. The $37.5M verdict was the largest motor vehicle verdict for Texas and in the top 20 overall in the state for 2024. In 2025, Lyons led a trial team of Lyons & Simmons lawyers to obtain a $109.5 million verdict in Bexar County, Texas against CPS Energy for a gas explosion that resulted in catastrophic injuries to his clients. The verdict is believed to be the largest negligence verdict in Bexar County history and one of the largest verdicts in Texas for 2025.
