Sean Williams

Licensed in Texas

Sean Williams is a trial lawyer at Williams Attorneys Pllc, a plaintiffs’ injury law firm active throughout Texas, representing Texans injured through the negligent or reckless conduct of people and/or corporations.

Sean also appears regularly in North Dakota courtrooms on a pro hac vice basis to argue oilfield injury cases including a 2020 trial resulting in the largest oilfield injury jury verdict ($9,000,000) in North Dakota’s history. See Landmark Cases.

Growing up as the son of nationally acclaimed trial lawyer Justin Williams, Sean learned the importance of injured people finding the best possible lawyer and the tragedies that can happen to a family if they make the wrong choice. Now working with his father and brother, trial lawyer Ryan Williams, Sean’s professional diligence is driven by the knowledge that his clients have just one shot at justice and it is his responsibility to ensure they get it.

Among the types of injuries Sean addresses are:

Among Sean’s multimillion-dollar settlements and verdicts for seriously injured plaintiffs and their families are several where the opposing parties were some of America’s largest oil and gas companies, with their expected armies of well-funded defense lawyers determined to deny justice to Texas and North Dakota families.

Never backing down from a difficult case, Sean helped secure the largest back injury verdict in North Dakota history where, during a rig move operation on an oil field, the client was struck in the back with a Kelly hose, leading to multiple back surgeries and spinal fusions. At trial, the odds were stacked against Sean and his co-counsel: there were no witnesses to the injury; the client had a past history of substance use, which brought up issues of possible medical negligence; and there was unfavorable medical testimony.

In another oil field injury case, Sean was on a trial team that secured a $4.7 million settlement for a man who was forced to undergo an at-the-knee amputation after a pipe rolled off a rack and smashed his leg. The pipe should have been secured with pin stops, but none had been used. The defendant argued that the plaintiff and his employer were responsible for ensuring pin stops were in place before beginning work, but Sean and his co-counsel proved that the duty fell on the company that stacked the pipe. Ultimately, the team achieved a very positive settlement for the client.
