WHo We Are

Experienced Trial Attorneys Dedicated to Excellence in Law

We are committed to those we represent. Our colleagues and judges respect us, and more importantly, so do our clients. 

  • When you need legal advice, time is essential. That's why we use state-of-the-art technology to ensure that our clients across the country receive the same personal attention and responsive service as our Oklahoma City neighbors.
  • As a testament to our service, we have built long-term relationships with a broad base of clients, including individuals, small and mid-sized businesses, and Fortune 500 companies. While clients may come to us for help with a specific legal issue, they often return for ongoing advice and representation because they appreciate our integration of business acumen and legal knowledge.
  • In fact, most new clients and cases are referrals from existing clients and other attorneys. Other lawyers frequently enlist our help in complex cases, and we are a premier resource for out-of-state attorneys seeking co-counsel in Oklahoma's trial and appellate courts.
  • Additionally, our firm is in the Bar Register of Preeminent Lawyers in America. This rating is the result of a peer-review system based on the confidential opinions of practicing attorneys and members of the judiciary.
