Biography

Over the past 20+ years of practice, Lyons has tried cases to juries, judges, and arbitrators throughout the state of Texas and all over the country. In the process, Lyons has obtained verdicts, awards, and settlements totaling over a billion dollars on behalf of his clients—many involving high profile, high exposure matters.

Lyons has extensive trial experience in cases involving catastrophic personal injuries, wrongful death, product liability, business disputes, construction defects, and professional liability. Lyons’ cases are as diverse and extensive as his approach to his cases. He has handled cases involving: brain and spinal cord injuries, electrocutions, aviation disasters involving helicopters and airplanes, trucking accidents, construction site accidents, industrial accidents, motor vehicle products liability, pharmaceutical, and medical device products liability, large business disputes involving breach of contract, fraud, and breach of fiduciary duties, medical malpractice, high profile contract disputes involving college football coaches and celebrities, and fire and explosion cases. In 2023, Lyons was part of a trial team that secured an $860 Million jury verdict for the family of a victim killed when a tower crane collapsed and fell onto an apartment building in Dallas, Texas. The incident and the trial was a national news story. In 2022, Lyons was named to the Plaintiffs’ Executive Committee in In Re: Astroworld Festival Litigation related to the tragic events involving the deaths of 10 people at the Astroworld Festival Concert in 2021. Lyons is among a handful of attorneys selected for the Plaintiffs’ leadership of this mass casualty litigation. In December of 2022, Lyons obtained a $10.1 million verdict in an emergency room delay case that was streamed live by Courthouse View Network. It was tabbed by CVN as one of the “Top 10 Most Impressive Plaintiff Verdicts of 2022.

Lyons has earned the respect of his peers through the relentless pursuit of justice for his clients. In 2021, Lyons was honored by the Dallas Trial Lawyers’ Association with the John Howie Award, which is given annually for the “courageous pursuit of justice in the face of adversity”. Lyons was given the award, in part, for taking a very difficult liability case to trial in one of the most conservative venues in Texas that involved the deaths of three African American children. The verdict is believed to be the largest in history for a wrongful death personal injury case in Midland County, Texas. Lyons has been recognized by The National Law Journal as one of the top lawyers in the country as a “Trailblazer” award recipient. He has regularly appeared on Thomson Reuters Super Lawyers listing (2005, 2008-2024), including being selected among the Top 100 attorneys in Dallas/Fort Worth (2018-2024) and was selected as one of the Top 100 attorneys in the entire state of Texas (2021-2022). He has earned Lawdragon Top 500 Leading Plaintiff Consumer Lawyers (2020-2023) and Best Lawyers in America (2019-2024) recognition. He was honored as a “Best Lawyer in Dallas” by D Magazine in 2005, 2011, 2013, 2015-2017, and 2019-2023 and is one of only a select few to receive the award for both personal injury and commercial litigation. Lyons has been recognized as a member of the Million Dollar and Multi-Million Dollar Advocates Forums, was named a Lifetime Achievement member of America’s Top 100 Attorneys for Texas, and was named among America’s Top 100 High Stakes Litigators in North Texas for 2017-2022. He has attained an AV® Preeminent™ peer-review rating from Martindale-Hubbell consecutively for 15 years, signifying the highest level of professional excellence based upon peer-review evaluation from lawyers and judges who have observed his legal skill and ethical standards.

In addition to pursuing outstanding results on behalf of clients, Lyons has invested significant time in the service of his community as a leader within the Dallas Bar Association and as a leader in his community. In 2008 Lyons was recognized by Dallas CBS affiliate KTVT Channel 11 as a "Texan with Character" for his philanthropic work in the Dallas – Fort Worth Metroplex with children who were victims of abuse or neglect. In 2010, he was elected as a Fellow of the Dallas Bar Foundation, and in 2015, Lyons became a Fellow of the Texas Bar Foundation.
