Your Personal Injury Attorneys

Hasbrook & Hasbrook is an Oklahoma City personal injury law firm founded in 2000 and now in its second generation of practice. Attorneys Clayton T. Hasbrook, T. David Hasbrook, and Roellen G. Hasbrook represent people injured by negligence in Oklahoma state and federal courts, with Clayton admitted to the Oklahoma Bar Association in 2008.

As a law firm built around community safety, we believe in the basic rule most of us learned as children: treat others the way you want to be treated. We expect drivers to follow the rules of the road and businesses, large and small, to act in the interest of public safety. When that expectation is not met, and someone is hurt because of it, the law gives that person a way to hold the responsible party accountable.

That is where choosing the right personal injury lawyer matters. Not every attorney who reviews a case takes it, and clients deserve a straight answer instead of excuses for turning down a strong case. We work to hold negligent parties accountable and to enforce the safety standards that keep Oklahoma communities safer for everyone.

The push for safety does not rest with lawyers alone. Ordinary citizens, including our clients’ families and neighbors, help drive it forward by pursuing the lawsuits that hold negligent parties accountable. Many of our clients pursue a case not for financial gain alone, but to help prevent the same harm from happening to someone else. Oklahoma juries, made up of local citizens, play a central role in weighing responsibility and awarding damages.

Clayton T. Hasbrook

Clayton practices in general litigation, with an emphasis on personal injury law. In 2005, he graduated cum laude from the University of Oklahoma with a Bachelor of Business Administration degree in Economics. While at OU, he served as academics chair, treasurer, and president of his fraternity, and as treasurer for the University of Oklahoma Young Democrats.

In 2008, Clayton earned his Juris Doctorate from the University of Oklahoma College of Law. He is admitted before all State Courts of Oklahoma and the Western District of Oklahoma, and he is a member of the Oklahoma Bar Association, the Oklahoma County Bar Association, the American Association of Justice, the Oklahoma Association of Justice, the Top 25 Motor Vehicle Trial Lawyers Association, and the National Trial Lawyers “Top 40 under 40.”

His practice focuses on civil litigation, with a primary emphasis in personal injury and insurance law.

Outside of work, Clayton spends time with his wife, their three boys, and two dogs. On a free weekend he can often be found tending one of his grills or smokers, or judging KCBS BBQ events as a certified judge.

T. David Hasbrook

David earned his psychology degree from the University of Oklahoma in 1975, then returned to OU for his law degree in 1978. From there he spent over four years on active duty with the United States Army as a lawyer in the Judge Advocate General’s Corps, building his early trial experience. He moved to the Army Reserves after leaving active duty in 1982 and stayed in uniform until his retirement as a Colonel in 2006.

David’s work is primarily in representing people injured by negligence, in both Oklahoma state and federal courts. His bar admissions cover every state court in Oklahoma, the state’s three federal district courts (Northern, Eastern, and Western), the Tenth Circuit Court of Appeals, and the United States Supreme Court. Over the years he has held membership in the American Trial Lawyers Association, the Oklahoma Trial Lawyers Association, the American Bar Association, the Oklahoma County Bar Association, and the Oklahoma Association for Justice.

Although David’s practice is centered on injury law, his background covers the full range of civil litigation. Early in his career in Oklahoma City he handled business litigation for both plaintiffs and defendants before shifting his focus to representing injured individuals. For the last two decades, he has concentrated his practice in personal injury and insurance law.
