As a law firm committed to community safety, we believe in the importance of upholding the fundamental principles that foster safer communities. We view safety not as an option, but an absolute necessity, an uncompromised standard of community living. This is based on a concept most people learn in kindergarten: treat others the way we want to be treated. We anticipate drivers to respect traffic rules, manufacturers to adhere to safety standards, and pharmaceutical companies to properly test their products to ensure they don’t cause unnecessary harm. In essence, we expect businesses, large and small, to act in the interest of public safety.

When entities choose to disregard this “golden rule”, society is obligated to hold them accountable. Should individuals, corporations, or governments falter in prioritizing the safety of its community, legal action becomes not just an option, but a necessity. This is where personal injury lawyers step in, facilitating enforceable accountability. We serve as the community’s sword and shield, combating negligence and advocating for those who have suffered due to it.

The power to enforce safety standards and initiate accountability is not solely in the hands of lawyers. Ordinary citizens, our friends, and family members, too, hold a substantial stake in this pursuit of justice. They bear the authority to instigate lawsuits, playing a pivotal role in the machinery of justice. Their experiences and their voices help prevent further tragedies and inspire others to act.

Many of our clients express a wish to file lawsuits not for personal, or monetary, gain but to prevent the recurrence of their tragedy in another family. Safety standards and the legal action that enforces them are crucial elements in ensuring the well-being of our communities. Juries, comprised of local citizens, are instrumental in determining responsibility and assessing damages, making a crucial contribution to upholding justice.

T. David Hasbrook

David attended the University of Oklahoma and obtained his undergraduate degree in Psychology in 1975 and his law degree in 1978. He then served over four years on active duty with the UnitedDavid Hasbrook States Army as a lawyer in the Judge Advocate General’s Corps. During this period, he gained valuable trial experience.

Most of David’s practice involves representing people who are injured as a result of negligence. His cases are in both state and federal courts. He is admitted to practice before: all state courts in Oklahoma; the United States District Courts for the Northern, Eastern, and Western Districts of Oklahoma; the Tenth Circuit Court of Appeals; and, the United States Supreme Court. At times, he has been a member of 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 primarily in the injury law arena, his experience involves all aspects of civil litigation. In his initial practice of law in Oklahoma City, his emphasis was in business litigation, both for Plaintiffs and Defendants. He later found more satisfaction and enjoyment in helping injured individuals recover for their losses or damages. So, for the last twenty years, he has concentrated his practice in the areas of personal injury and insurance law.
