Established in 1887, Thompson & Knight today is a law firm of more than 300 attorneys. We have U.S. offices in Texas, New York, and California, and international offices and associations in the Americas, North Africa, and Europe.

In addition to providing a wide range of traditional legal services to clients in many industries, the Firm takes great pride in our depth of experience in the energy industry. Thompson & Knight is one of the world's premier energy firms, with a particular emphasis on finance, business transactions, and an ability to resolve our clients' controversies in or out of court. The Firm has counseled clients in 118 different countries – well over half the world.

To successfully leverage our knowledge base throughout the world, the Firm has made a significant investment in technology, which allows us to provide the best possible service and value to clients. The Firm has received national recognition for the use of technology and regularly employs cutting edge tools and applications to assist both lawyers and clients in reaching superior results.

Thompson & Knight creates, fosters, and maintains a meaningful and substantively diverse and inclusive workplace, environment, and culture. The Firm promotes diversity in thought and action through the organizations we support; the companies with whom we do business; the clients whom we serve; and the employment, development, and advancement of a diverse body of highly valued personnel. The Firm has taken crucial steps toward reaching the goal of becoming the diversity and inclusion model for our legal communities. Thompson & Knight was the first Texas law firm to hire a Chief Diversity Officer.

We believe that our culture, which emphasizes teamwork and an unqualified commitment to excellence, is a key reason for our success. 122 of our attorneys were selected by their peers for inclusion in The Best Lawyers in America® 2017, placing the Firm among the most highly recognized law firms in the country. Among many other distinctions and honors, the Firm has been recognized as a "Best Place to Work" by the Dallas Business Journal (for 12 consecutive years) and the Houston Business Journal (for three consecutive years). Thompson & Knight has been named “Law Firm of the Year” in Oil & Gas Law in U.S. News-Best Lawyers® “Best Law Firms” for 2011-2013, 2015. 

Thompson & Knight has always been a client-centered, results-oriented law firm that prides itself on the ability to reach creative, thoughtful, and effective business and legal solutions. We are proud of the distinguished academic honors and many professional awards and recognition our lawyers have received, but are perhaps even prouder of the ability of our lawyers to listen and be responsive to the needs and goals of our clients.
