    “The Best Lawyer for a time in your life when you need the truth!”
    I had a nasty divorce going with my ex-wife who was using one of the High Power Dallas Lawyers that was intent on making things difficult and costing both of us most of the money we were fighting over. Duane was able to calm me down and came up with an idea for the settlement that not only saved me and the ex money, but actually made his fees LESS EXPENSIVE!!! You will not hear of that many times with any lawyer. I would recommend him for a simple divorce or a complex one with all of the circumstances that always make things difficult. He just has a way of working things out with all parties that make so much sense the case gets settled and everyone gets what they want.

    “Need a good, trustworthy and dependable lawyer? Well Duane Coker is your man!”
    I have only been through a divorce once in my life and I thought I would hire a "big name" lawfirm in Dallas to handle my case. Well long story short, all the "big name" lawfirm did was rake me over the coals for money then dropped me like a bad habit after they sucked me dry! I immediately started looking for another lawyer locally in the Denton area and was referred to Duane Coker. I was reffered to Duane by another lawyer that doesn't specialize in divore or family law and was told he would treat me right. Well they were right! He made me feel very comfortable and told the the honest truth about things. He saw what my previous lawyer did to me and what my wife's attorney was doing to me. I am so glad he took my case and got my divorce finalized! He was very up front with things and kept me in loop on everything. The only regret I have is I should have used Duane from the begining! It would of had saved me thousands of dollars and a lot less headaches. I can't say enough good things about Duane and his staff. What a "true" lifesaver they were to me!

    “great help with my modification”
    Coker Law Firm represented me in my modification case. They were very informative and helpful throughout the entire process. They were also very patient and very persistent when opposing counsel was slow to respond. With their help, I was able to resolve my modification to my approval without compromising. I would recommend their services to anyone needing a family law firm.

    “I would highly recommend him to anyone.”
    I have used Duane Coker for several legal issues over the past seven years. Each time he was always honest with his advice and very aggressive in pursuing my best interest in the situation. I would highly recommend him to anyone.

    “He patiently listened and offered superb advice on how to proceed, all without asking for anything in return.”
    Duane and I have a mutual friend and business associate. I was well into a legal matter, and Duane very graciously spent over a full hour on the phone with me. He patiently listened and offered superb advice on how to proceed, all without asking for anything in return. I can’t recommend him enough. Very smart, honest, and a genuine nice man.
