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, insurance law, and employment law.

I couldn’t be happier with Clayton. He’s actually the second attorney I hired on my case. The first law firm had my case for a year and then said ‘here’s your settlement, we recommend it, and it’s all we can get you, but take it or leave it, this is a good settlement for your type of small case.’ It was barely anything. After parting ways with that law firm, I hired Clayton about a week or two later. He worked on my case more in one month than the previous law firm and was able to settle my case for close to 2x what the earlier law firm could do. He also charged less than what the other firm wanted….25 vs 40%. So, I was very happy with the result and to finally get my case over with – so frustrating!
