TESTIMONIALS

  • Professional, respectful and knowledgeable, honest from the first moment of our first discussion. He explained me every scenario with details and got the best possible outcome for me. I am totally glad he was representing me and I definitely recommend him as your attorney.

    - John

  • I am so glad that I contacted Mr. McMahon for help when I needed an attorney for my forest preserve violations. He was professional, kind, and most importantly did not judge me. He is clear and up front about the legal process and communicates what you need to do and what he will do for you.

    - Allie

  • Mr. McMahon helped me find a rehabilitation treatment center, he talked with me, made me want to turn my life around while I was facing serious charges: DUI, possession of uncontrolled substance, and more... I wouldn't be here without him. He gave me hope.

    - Satisfied Customer

  • I want you to know I did not like Mr. McMahon, I LOVED HIM. He believed in me and what I told him happened, he read the reports, and watched the video, and could see that my story was correct. And when he discussed my case with the Judge, they decided all charges should be dropped and found me NOT GUILTY.
