Welcome to the Merman Law Firm

The Merman Law Firm is dedicated to providing personal service to those injured by the negligence and intentional conduct of others. The Merman Law firm only accepts a limited number of cases each year and provides exceptional effort, support, caring and excellence in vindicating the rights of its clients. Mr. Merman focuses his attention on cases involving important social issues, serious injuries and negligent corporations.

The Merman Law Firm is a serious trial firm. Mr. Merman won two verdicts in excess of $10,000,000 before turning forty years old – in addition to millions of dollars in hard-fought settlements and verdicts. The Merman Law Firm refuses to settle for less than a case is worth, preferring to take the case to trial where Mr. Merman is a proven winner. The Merman Law Firm is fearless and has taken on corporations such as Johnson & Johnson, E.I. DuPont de Nemours, Cooper Tire and Rubber Company and the City of Houston. By being extremely selective in taking clients, the Merman Law Firm insures that it has the resources, time and attention to vindicate its clients’ rights against any person or company – no matter the size.

As a leading personal injury lawyer, success has not jaded Mr. Merman. He remains caring and compassionate with all of his clients. Because he maintains a small docket, his clients are like family to him. Mr. Merman lost his father in a plane accident caused by a negligent plane manufacturer and he has not forgotten how important a skilled, caring and compassionate lawyer is.

“My experience with Mr. Merman and his associates was fantastic.  I was impressed by the professionalism with which my case was handled, as well as with the results of my settlement. Derek is very knowledgeable, skilled, and personable;  I recommend him without reservation. “

-Ms. Painter

“Derek Merman is a consummate professional, he communicated with us at every turn and treated us with dignity and respect. Mr. Merman always took the time to listen and explained every step of the way. Mr. Merman and/or his staff was always on hand to answer any questions we had or supply us with information. We always felt like we were a part of the process. Our case was handled with the utmost satisfaction and I recommend Derek Merman to everyone in need of legal services.”


“It is rare to find good attorneys these days, so I considered my self extremely fortunate to have been referred to Derek to help me get through a very rough accident claim. He epitomizes the definition of professionalism. I knew when he said he would take care of it or me, he meant it…because he did at every turn. He has since become my personal friend and an adviser I have come to respect and appreciate. He has represented me and my oldest son on two separate cases. I highly recommend Derek Merman for your legal needs.”

Warmest Regards,

"My name is David Morris, I've known Derek Merman for almost 15 years. We went to law school together, and he's always been one of the smartest, hardest working, and most loyal people that I've known which are great qualities to have in an attorney. I know that if something were to happen to me, I would trust Derek to represent my family."
