Greg brings his clients over two decades of experience as a tenacious, creative trial attorney. His reputation and successes have earned the respect of his peers, as he has been recognized by Super Lawyers® throughout the years for his professional achievements.

Greg has tried cases for plaintiffs and defendants in courtrooms and arbitrations both in and out of Texas. For over a decade, he has served as “national counsel” for a large corporation, overseeing its complex litigation docket across the entire United States. He has recovered millions of dollars for plaintiffs and, when wearing the other shoe, has obtained defense verdicts when his clients faced the possibility of multi-million dollar judgments.

Greg is routinely called upon to handle “bet the company cases” involving complex issues, largely due to his innate ability to pare down the complicated so a judge or jury can understand his clients’ story. As a trial lawyer, he tackles cases of all kinds, but usually handles cases involving complex business disputes, construction defects, catastrophic personal injury, negligence and product liability.

A Dallas native and proud Aggie, Greg earned his Juris Doctor from the University of Houston and spent nearly the first half of his career in Houston before he found his way back home. Prior to founding the Firm with Michael Lyons in 2008, Greg was a partner in a large Texas-based litigation firm.

Diffuse Tensor Imaging & Advanced Imaging Techniques

One of the biggest hurdles brain injury victims have in personal injury and products liability cases is quantifying the degree of injury to the jury. If a jury can’t feel or discern the extent of a person’s injuries, they are less inclined to award damages. We have effectively utilized cutting-edge advanced imaging techniques such and diffuse tensor imaging or DTI in cases involving brain injuries. With this technology, a jury can confirm that an individual has no injury and should not be awarded damages for a significant brain injury or, alternatively, such as in the case of the example provided, that the individual has suffered injuries throughout the brain. When paired with a history of trauma and an absence of some other explanation, this evidence has become the gold standard for confirming brain injuries. You can click on the player to see a 3-D rendering of the brain made by DTI.

Trial Animations

Trial animations can be incredibly impactful if used properly. Sometimes a concept or complex scenario is described, but only a picture can shed light on what really happened. Having the ability to show and explain a client’s position using trial animations is a compelling way to get the point across. Understanding the proper way to create and utilize these tools is just as important as putting together the evidence that supports them. Often times, a creative animation can be the difference in having a successful outcome at trial.

Trial Illustrations

Presenting information that a jury can see and understand is so critical to a good outcome at trial. Whether it's understanding the gravity of a particular injury or ascertaining how an accident sequence occurred, proper illustrations that call the jury, judge or arbitrator's attention to what's important in a way that is impactful is a critical component to our trial teams. Here are some examples of our trial illustrations.
