Peter Cawthon

Attorney (of counsel)

Peter W. Cawthon IV is Of-Counsel for Martinez Hsu and manages the Construction, First Party Plaintiff Insurance, and Personal Injury areas of practice at the firm. Peter graduated from the Texas Tech University School of Law and is admitted to practice in various Federal District courts. Upon graduation from law school, Peter took a different path by pursuing a career in commercial construction and learned the business from the ground up and has been involved in various multi-million dollar projects from sales to project management and handing over the completed project. That unique perspective allowed Peter to re-enter the legal field and help contractors and property owners solve not only insurance dispute issues but also general litigation, contractual, and business issues. Peter was raised in Oaxaca, Mexico as a missionary kid and speaks fluent Spanish, a skill that has helped both his construction and legal careers. He married his wife, Ana, while in law school as she was completing her Ph.D. They have two sons: Peter (V) and Noah. When not diligently working for his clients, Peter enjoys anything outdoors. While in Mexico he summited the third tallest peak in North America and has also kayaked through hundreds of miles of rivers in Texas, Michigan, Mexico, and the rest of North America. Peter's unique upbringing and moral fiber drive him to provide fair and dedicated services to his clients and to ensure that they receive the best possible outcome from their legal issues.
