Mark is great, respectful and very knowledgeable about his practice. Before I hired Mark, I felt very overwhelmed with how to handle the divorce and what to expect. Mark guided me every step of the way, and took a lot of the stress out of the whole process for me. He was there to answer any and ...

"I have known Mr. Williamson for many years, and have had cases with him, and against him. He is poised, firm, intelligent, an excellent communicator and exceptional in the courtroom. I highly endorse this attorney."
"I endorse Mark Rush Williamson. I have know him for over 35 years. He is a man of character and a skilled advocate for his clients. Hire him before you spouse does."
"I highly endorse Mark Williams. We have had a case opposite each other, and he worked hard to resolve tough issues. Mark is a great negotiator who puts his client’s interests first."
"Mark is an extremely intelligent, creative and aggressive advocate. He will not back down from a tough case, and he is at home in the courtroom. I endorse this lawyer."
"I endorse this lawyer. I have drawn several cases as opposing counsel to Mark over the last few years and have found him to be both an excellent advocate for his client and a man of integrity."
"I had a case against Mr. Williamson in 2011 and in all my dealings with Mark I found him to be an extremely intelligent, tough, and well prepared attorney that definitely knew his stuff. I'll always remember that despite the years of experience he had on me, he treated me with respect throughout the process. Although tough in the courtroom, his demeanor with fellow lawyers behind the scenes was exactly how it should be. Mark knew when to be diplomatic and also when to flex his legal muscles. I learned a lot going up against Mr. Williamson, and even modeled some of my own practice methods after his. In addition, his office staff was always unbelievably courteous and helpful, even though we were adversaries. I highly recommend Mark Williamson to anyone seeking a family law attorney, and to be honest I'd probably choose him if I ever needed a family attorney myself."
"I've tried a case against Mark and found him to be a tenacious (distressingly so, for me as opposing counsel) and skilled advocate for his client. Anyone looking for an attorney to represent them in a family law matter would do well to have Mark in their corner."
"Having practiced divorce law for over 16 years, I have had the opportunity to tangle with some of the best lawyers in the DFW area as well as some of the worst. I certainly am not itching to be divorced from my own wife, but if it were to happen, Mark would be on the short list of lawyers to whom I would turn to handle my own affairs."
"I endorse this lawyer. Mark is a phenomenal lawyer with an exceptional reputation in the Dallas/Ft. Worth metroplex. He goes above and beyond to help his clients."
"Mark is a tremendous lawyer. I know from experience. He whipped me pretty good, but I learned from the experience, and I am a better lawyer for it. To be the best you must learn from the best."
"I endorse this lawyer. I have known Mark for many years and had the opportunity of working with him as opposing counsel on a case. Mark is always professional and his knowledge of Family law is exceptional. I would recommend Mark to anyone who has a Family Law need."
"Mark Williamson is an exceptional attorney. He is a fine litigator and he also knows when a case needs to be settled. I recommend Mark without reservation."
"Mark Williamson is an excellent lawyer and is respected by his peers. He handles every case with a personal touch that his client's seem to cherish. I have heard nothing but positive things about his relationships with clients and I know from personal experience that he is a skilled adversary. I recommend Mark to anyone with a family law matter."
"Mark is an excellent attorney. He has been on the other side of several cases and is tenacious is highly professional."
