Impressive attorney who doesn’t miss the details

Mr. Merson represented a family member in a difficult traffic situation that had many nuances to the case. Jim was incredibly thorough, and found many unlawful operating procedures on the law enforcement side of the case that gave us a very, very strong position. Mr. Merson’s attention to detail... and his knowledge of case law was beyond impressive. Due to these factors the Family member received the best possible outcome from the case. I would highly recommend James Merson to anybody looking for a highly efficient, yet kind and caring attorney that really goes the distance for his clients.

Incredibly competent, kind and professional.

Mr. Merson was fantastic throughout my entire process in municipal court. I was concerned with my situation and had no clue where to begin. He went above and beyond to explain, advise, and reassure me of the entire process from start to finish. He handled all essential communication with all parties ...and consistently kept me updated. He made a scary and unknown process clear and concise. The difference I felt in having Mr. Merson defend me compared to other lawyers I saw was incredible; he was incredibly knowledgeable about the entire process and had my back as a client. Highly recommend.

False advertising

When you first go into Mr. Merson’s website, you’re greeted by a greeting that says he’s knowledgeable and he knows what he’s doing. But as soon as you get to the court dates and the DAs start putting the heat on him, he buckles. he claims to be knowledgeable in DUIs but is not, I was on probation fo...r my second and I had gotten pulled over for a third. With mandatory jail sentences on both, I had already served one and he let me miss out on a week of my life. I highly recommend going to someone else

DUI TO DWAI

I found Jim online and turned out to be the best decision I could have made for my situation. He was very attentive to my case and very knowledgeable in dui law. I was charged with DUI with a very high BAC and Jim was able to get it knocked down to a DWAI. I appreciated his professionalism and w...ould highly recommend his services to anyone facing a DUI charge.

Marijuana case and illegal search

James Merson went above and beyond what I would have expected from a defense attorney. He impressed me through and through with true concern and respect for me and my case. He had fresh ideas on how to approach my case which showed me he was truly giving me the time and consideration that I deserved.... I had violated my current probation in California when I was arrested in Colorado for pretty much the same thing so I was a bit nervous, to say the least. I was so concerned about my case that I did a little shopping around and another respected local attorney said I was in good hands with Merson. After a motion to suppress the evidence filed by Merson was granted by the judge, I thought I was in the clear and was celebrating. I thought I won. About a month later Merson calls me to explain the DA appealed the judge's decision to the Colorado Supreme Court. WTF?!?! That can happen?. Well, it can and did. Could I really trust him with years of my life on the line? Is he going to give me the best defense I deserve? Christ this case is for marijuana in CO. My case continued to the state supreme court where Merson and I again felt total confidence that our motion to suppress the evidence would be recognized as correct and upheld at the state level because it was clearly an illegal search. Merson always responded to my calls and texts even though I'm sure I behaved like I was his only case. I still can't believe that only two of the seven State Supreme Court judges agreed with our position. No matter what Merson was ready and willing to continue the fight for me. God, I wanted to but I had to consider a lot, time, being the main thing. I chose to take a plea which continued to be a headache. Let's not forget during this whole proceeding, which took 2 years, I was technically a fugitive from my original probation in California. Merson even called my probation officer and lawyers in California and was able to arrange a deal to terminate my probation in California, unsuccessful of course, but terminated based on, I was going to be Colorado's problem. Colorado was gonna send me to prison, probation, a program or whatever. Making that happen was no joke since I was facing up to 8 years just in Colorado not including what California could have given me. I'm now one year into 5 years of probation and my 90-day jail sentence. James Merson used all of his knowledge and skills to provide the best representation I could possibly have. But truly the best lawyer I could have had. Now he's able to help you with his own practice and trust you want him working for you! I'm eternally grateful to him. Thanks buddy!
