About Derek

Learn Derek’s areas of practice.

Derek was born and bred to be a trial attorney.  The son of a successful attorney who died as a result of a negligently maintained airplane, Derek was raised by his mother on their ranch near Waco, Texas.  For obvious reasons, Derek is passionate about his work for the injured and those who have lost loved ones because of someone’s negligence.

Derek is a fearless litigator.  He has single-handedly recovered settlements and verdicts from some of the biggest companies in America and the world, including Union Pacific Railroad, Cooper Tire and Rubber Company, Nationwide Insurance Company and dozens of others.  Derek has represented injured people and surviving loved-ones all across the globe.  He has been recognized as Metropolitan Magazine’s “Who’s Who”, Texas Monthly Magazine’s “Texas Rising Star,” and “Top 100 Trial Lawyers in Texas” by ATLA.

Derek does whatever it takes to fully compensate his clients.  If that means taking the case to trial then Derek and his clients have the advantage.  Derek typically tries several cases a year to successful verdicts.  Not only does he win, but he wins big, including obtaining the largest individual civil rights verdict in Texas history – over $16 Million in January of 2011.  Again in March, 2012, Derek was co-lead in a trial against DuPont where the Jury returned a verdict for $11,965,000 for his clients.  Over his career, he has collected millions of dollars for his clients.

Review of Mr. Derek Merman
My wife had a premature failure of one of the hip joints. Mr. Derek Merman took a lot of personal interest in this case and we had a decent recovery from the joint provider company. Mr. Merman is very hardworking, honest and sincere person. He is very reliable and trustworthy and dependable.

Excellent Lawyer
My experience with Mr. Merman and his associates was fantastic. Derek was prompt and honest with us after our auto accident. This was my first accident and both Derek and his paralegal were great at explaining the process and helping us get what we deserved without a hassle. He is fair and has only his clients in mind. I would highly recommend the Merman law firm for any of your personal legal needs.

Personal injury Attorney | Oct 04
Relationship: Worked together on matter
"I’ve known lots of smart lawyers, and Derek is not only one of the smartest, but he also has a creative approach to handling cases that makes him very very effective. He is always focused on winning, and he is one of the hardest working and most prepared lawyers I’ve ever known. It’s not uncommon at all for Derek’s clients to hug him and cry at the end of their case, and he often keeps in touch with them forever. He treats his clients like family!"

"Derek Merman is incredibly tenacious and hard working. He knows his way around the courtroom and is not afraid to battle for the little guy. I collaborated with Derek on a few cases where his clients had corresponding criminal matters. His clients absolutely love him, and he goes above and beyond for them. Most recently he obtained a multimillion dollar judgment for a client who was injured after a tire explosion. Despite the billion dollar empire battling Derek, he obtained an amazing outcome for his client. I know the client will never forget him. I am always eager to work with him whenever presented with the opportunity."
