Great Lawyer!!! Highly Recommended!!!
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 all questions I had. He is very quick to respond via email with any concerns I had. He is very confident in his work and it shows. I was very impressed with the way he treated and respected my case. Mark worked very fast and very diligently on my case as soon as I hired him. Mark definitely made the divorce go very smooth, far beyond what I was expecting. His concern for his clients case and well-being was very well received. I highly recommend Mark R. Williamson if you need help with divorce and separation. He's a very knowledgeable professional who truly cares for his clients.

Excellent representation
I am truly great full for the Williamson Law Firm! Communication was spot on throughout the entire case. The firm was respectful and professional of all parties in this case and they treated my case as if it were their own. We were able to achieve our goals in a timely manner. Again thank you for representing me in my case.

"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."
Family Attorney | 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."
Family Attorney | Apr 16
Relationship: Opposing Counsel on matter
"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."
