Committed To Exceeding Expectations

We are regularly retained as lead trial counsel for both plaintiffs and defendants in major commercial litigation both inside and outside of Texas. While we are customarily retained at the outset of the litigation, we are not infrequently retained to either join existing counsel as lead trial counsel or to substitute for existing counsel prior to trial.

Our trial experience encompasses a wide range of substantive areas, including significant commercial litigation and virtually every aspect of oil and gas and natural resources litigation. In recognition of our level of experience in trying cases and our track record of successful results, Jesse Pierce and Jack O’Neill were each included by Lawdragon in its 500 Leading Litigators in America Guide for 2023.
