In Their Words

Client Reviews as Published on Martindale-Hubbell

“Mr. Fred Dietrich and his team represented me throughout a lengthy and complex legal matter. They carefully reviewed the facts and documents, considered the case from different legal perspectives, and consistently worked to protect my interests. Mr. Dietrich is highly professional, knowledgeable, patient, and detail-oriented. He clearly explained the legal issues, possible outcomes, and available options, which helped me make informed decisions throughout the process. His team was responsive, accessible, and easy to communicate with. Litigation can be extremely stressful, but Mr. Dietrich’s guidance and support gave me peace of mind and helped reduce that burden. I am very grateful for the expertise and dedication of Mr. Dietrich and his team. I strongly recommend The Dietrich Law Firm to anyone seeking an experienced, professional, and compassionate legal team.”

“We hired Fred Dietrich, a colleague (I am a lawyer myself), in a private claim against a Texas company and were very satisfied with the entire process. Not only have we been able to assert our claims, but we have always felt well advised. If I ever have another case in Texas, I will definitely hire Fred Dietrich again!”

“It was a good experience working with Fred Dietrich. We had written to some lawyers beforehand, but our case was too void for them. We were looking for someone with whom we could also work well from abroad. He took on our case and got the opposing side to transfer the payments due. Fred Dietrich is really recommended!”

“Fred did an amazing job on our case! Very responsive and kept me cool during the whole process. I came in thinking this case would drag out. Because of Fred, we closed our case in less than 2 months and he was able to negotiate a wonderful deal.”

“Unfortunately, with many lawyers one often feels they are running the clock without a plan or getting anything done. Fred was knowledgeable, direct, kept us informed and had a result better than we anticipated. We would definitely hire him again and definitely recommend him to others.”

“Fred helped us greatly with our case. He was so valuable to have on our side of the dispute. Definable as a perfectly executed defense. Thank you for all you accomplished, Fred.”

“The Great Fred Dietrich — unlike no other attorney I have worked with. He is great and responsive.”
Posted by AnonymousJune 20, 2018
“I have significant worldwide experience with a large number of law firms and lawyers. As in any service business, there are those who rise above the norm and those who really stand out. Fred is not only an exceptional lawyer, but he is extremely bright and his billings are among the most honest and fair out of any lawyers I have ever worked with in my business career. I would not recommend any commercial litigation lawyer in Texas except for Fred Dietrich if you want to be treated honestly!”

“Aside from his excellent legal representation, Mr. Dietrich was always very prompt and fastidious about returning my calls or responding to email inquiries. His attention to detail always made us feel that we were his most important client. He always exuded a confidence and professionalism which made us feel that we were getting the best legal representation possible. We also found his fees to be very reasonable.”
