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.

Les Hartman has outstanding knowledge. What i really like about Les is that he takes the time to explain everything about the case. Les is down to earth and is very understanding and someone that is easy to talk to. That matters to me when you are going through something. Les Hartman thanks

Simply and by far the BEST around

Ived used two other lawyers in the area for more simple issues in the past, but recently needed the best. I hired Mr. Hartman and all expectations were exceeded. When first meeting he told me the best possible scenario and the most common scenario, and months later it ended in the best possible scena...rio. I highly recommend him, he couldnt have possibly done any better for me, and he made me feel like he actually cared about me as a person and cared about the outcome of my legal case. Thank you Mr. Hartman, I appreciate you.

Great attorney ... Great results

Mr. Hartman was recommended to me by word of mouth. He was very professional, straightforward and compassionate. He handled my case exactly as he said he would and I was pleased with the outcome, which was a better result than I had hoped for. I highly recommend hiring him for your legal needs.
