    “Best lawyer you will ever find”
    I have to say, when I hired Brent Langdon in November 2013, I was a very hopeless, desperate person. My daughter had been turned over to her father when I did not show up for a court date. I was not properly notified of a court date by him nor his attorney. So, I decided, "I'm tired of this. I'm going to find the best lawyer I can find." So I went to Langdon Davis. Initially, I was there to see Demaris Hart. However, she was not there at that time (I did not have an appointment with her, I just walked in the office). I spoke with the woman at the front desk about meeting with Demaris, and she said she was not there at that time but there was another attorney who I could talk with about my case. I went back and spoke with Brent about my situation and he said he'd take it on. A few months later, we had a court date and got the order my ex filed overturned. My ex has consistently given me problems since then, though. We have been in and out of the court room from day one, with him trying to take our daughter away from me. Brent Langdon has stuck by my side through every bit of it. Not to discredit Demaris whatsoever by this statement, I have read her profile and know she is a great attorney also, but I am SO glad I hired Brent. That was the best decision I have ever made. This man has LOYALLY stayed by my side through all of this litigation. He has fought for me and my daughter from day one. And I'm glad to say, last week we won our case. If you are looking for an attorney to help you, guide you, be prepared for your case without any worry on your end, and most importantly FIGHT for you, this is your lawyer. Trust me. You will see the passion he has, and the incredible law knowledge he has studied 25+ years for. Respectfully submitted, A PROUD Brent Langdon client
    “Brent was everything and more.”
    He was tough with negotiations. At the end of the day he was able to get a deal that wasn’t only fair for me but for my child. After hiring a less than average attorney I realized quick you get what you pay for, I then hired Brent . Brent is expensive but hes good, fair and honest. I’d recommend Brent to anyone in Arkansas or Texas.
