I worked with Marc and am very impressed and happy with results. He is very knowledgeable and personable. He guided me through the whole process, was easy to reach, and very responsive. Marc took the time to answer all my questions and explain everything to me. The rest of the team were great too. Highly recommend.

I am so thankful that I retained the services of Marc Gann to handle my case. I had interviewed several lawyers to represent me and Marc Gann was by far the most personable and knowledgeable. As I worked with him I was always impressed by the depth of his knowledge and that he genuinely cared about me and my situation. Marc clearly explained everything to me at every stage of my case. Anytime I called his office my calls were promptly returned and Marc would take the time to patiently answer all my questions. I never felt rushed and I was always very satisfied with his responses. Considering his extensive expertise in law, I was amazed at how reasonable his fees were. I highly recommend Marc Gann for any legal issue that may occur in life.

I thought I would never see my family again. Then, I was introduced to Marc. I knew from the first meeting that he was special and could and would help me. Marc was always a quick phone call away and answered my questions professionally and compassionately. I felt like I was his only client. I did everything Marc told me to do. With his help, my misdemeanor was dropped to a violation. I have been home now for a year and have Marc Gann to thank!

Marc Gann represented me when I was charged with a felony and he was able to get the charge reduced all the way down to a non-criminal violation charge of disorderly conduct. Marc is an expert at what he does. He is truly respected in the court room and was attentive and committed to me every time we appeared in court. Thanks to Marc Gann I have a bright future and I cannot recommend him highly enough.

Marc Gann is an excellent attorney. He represented me and all charges ended up being dropped. He made sure I was informed of all my options as the case progressed, and advised me of the repercussions of each option. I would definitely recommend him to anyone facing criminal charges.
