After 23 years of DUI work, I am pretty well versed in what to look for in a report, but when I got his work up, I was blown away. He spotted issues I had missed and cited all of his work. He did an extensive and well-detailed analysis of the videos and report and wrote up his findings in such a way that made it easy to use in negotiations. I was so impressed that I immediately hired him on many more cases, and his work has continued to blow me away. I now consider Mr. Marshall a must-hire on any DUI case.
Initial conversations are brief, confidential, and without obligation. Conflicts are screened before any case material is reviewed.
