We Are Trial and Appellate Lawyers

You cannot make up trial and appellate experience. You must have undergone it.

Mr. Pierce and Mr. O’Neill each have more than 50 years of experience in the trial and appeal of high stakes civil litigation for commercial and energy industry clients. Although most often retained at the outset of a matter, the firm is frequently asked to substitute as trial counsel, or to step in as appellate counsel. Clients, other attorneys, and companies widely regard the firm as the first choice for significant, complex litigation. The firm has repeatedly been recognized as one of the nation’s top law firms by Best Lawyers®, and a “Go-To Law Firm” by in-house law departments at Fortune 500® companies.

Mr. Pierce and Mr. O’Neill are members of the American Board of Trial Advocates. Both have been recognized by Chambers USA, named to Lawdragon®'s 500 Leading Litigators in America, included in Best Lawyers® as leading practitioners in multiple practices, selected for Texas Super Lawyers®, and earned AV Preeminent ratings from Martindale-Hubbell®.

Preeminent in Complex Business and Energy Litigation and Appeals

We are a litigation “boutique” with a single focus — the devoted and accomplished representation of our clients. There are major differences between trial lawyers, on the one hand, and “litigators” who primarily engage in discovery and motion practice, on the other hand. We are a firm of accomplished trial and appellate lawyers. We excel at litigation and appeal.

Our reputation is built on experience and results that exceed expectations. The pursuit of our clients’ best interests is accompanied by a spirit of cooperation in the lawyer-client relationship. We undertake substantial matters on a regular basis for both new and existing clients and place significant value on our client relationships, many of which span decades.
