Hire this Attorney

What can i say? Counselor Hartman has been nothing short of stupendous. The circumstances we were complicated and required his expertise. The results were beyond anything i could have hoped for. The support and guidance from the staff was exceptional. I strongly recommend Hartman and Duff.

He takes the time with his clients

Mr. Les Hartman was very helpful with my case. He took the time to explain everything to my husband and myself. I am so glad that we retained him because without his expert advice we would have never gotten the excellent result that we did.

Your GO TO lawyer.

I can’t thank Hartman Duff enough for what he did for my cousin. He was falsely accused by an ex-lover of strangulation, assault, and making threats — extremely serious charges that could have ruined his life. These accusations were completely fabricated, but once you’re in the system, it feels like ...the deck is stacked against you. From the very beginning, Hartman stood out. He listened, explained the process clearly, and gave us confidence that the truth could be proven. He never treated the case like just another file — he was fully invested, reviewing every detail and preparing for every possibility. In court, Hartman was exceptional. Calm, sharp, and strategic, he tore apart the false story and presented the facts with precision. Thanks to his relentless work, the case was dismissed. What makes him even more remarkable is his compassion. He treated my cousin with respect, kept us informed, and truly cared about the outcome. If you need a skilled and trustworthy defense attorney, I highly recommend Hartman Duff. He gave my cousin his freedom back and our family peace of mind.

I highly recommend Les!

I highly recommend Les! Les was awesome. Very down to earth and easy to talk to. Between him and Angela, they made me feel better about my situation and helped me every step of the way through the process.

Excellent Attorney!

Mr. Hartman is an excellent attorney! He is highly knowledgeable and professional and a pleasure to work with. It was very easy for me to communicate with Mr. Hartman and know exactly what was going on throughout the legal process and what my options were. Mr. Hartman battled for me and resolved my c...ase as quick as he could. I cannot thank him enough for all that he has done for me and I would highly recommend him to anyone in need!
