A True Blessing From God!! Best Attorney Ever!!

Mr. Williamson went over and beyond for my son and I. I will forever be greatful because of him I have my son back and my family and I have a peace of mind. I truly believe God sent him and his paralegal Monica to our family.. Thank u for everything.

A True Professional

I was told to get a barracuda lawyer to help me with my divorce. Mark is a very thorough and professional lawyer. I felt he had great integrity and was well respected among his peers. I was always well informed and felt totally secure and confident in his leadership and abilities. Not once did I ...lose my joy or peace throughout the whole divorce process as I knew Mark was procifient and skilled in my interest. I had the Lord on my side too...so hey...how could I lose having God on my side and one of the best lawyers in Texas. Aside from the exorbitant attorney fees, which I was not prepared for, I am most satisfied with Mark Williamson and would recommend him to anyone who needs outstanding representation in the court system of Texas.

Texas Super Lawyer!!

Mark is the best of the best. When he gets into "trial mode" you almost feel sorry for the other side because they don't stand a chance against his no holds barred approach. Mark handled our custody case with skill, professionalism and compassion. He seemed truly concerned for the safety of our ...child and got us more than what we could have hoped for. I've recommended Mark to family and friends and they too have been beyond happy with the results Mark Williamson has achieved for them. He and his staff were always there when we needed them, whether it was to answer questions, explain the upcoming process or just to reassure us. If I ever need an attorney for a family matter again, Mark Williamson will be the first call I make.

Mark Williamson - Family Law Review, top of the line!

Mr. Williamson was highly recommended to me by a friend who I known for many years. My friend and I go long ways into the past and have referred many people to each other. But in this case Mark Williamson exceeded my friend's recommendation and my expectation as well. My legal quandary was beyond... grave and representing a life change event. Mark Williamson has been a great help in my case going beyond the call of duty. Mark Williamson is responsive, knowledgeable, always in touch and always reachable. He has always reassured me with great support and personal involvement by getting to know my needs and attending to them diligently. His practice methods and the carrying of the case are excellent, clean, transparent and with no false expectations. I would for sure recommend Mr. Williamson to anyone in case of distress.

Family lawyer | May 22

Relationship: Opposing Counsel on matter

"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."

"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."
