I have known Mark for over 20 years and I knew that he had worked hard to become one of the top DUI lawyers in Arizona. So when I found myself in a potential DUI situation he was the first person I called. I work in an industry with high net worth clients and I knew my arrest was not right, but if I was convicted could have major damage to my career and livelyhood. Mark did an excellent of job of keeping me calm and laying out the process for me step by step. He took me through each scenario and what needed to happened. I was able to continue my life and my work as Mark did his job. By Mark painsteakingly going throughout every nuance of my situation he was able to build case that ultimately reduced my charge from a DUI to civil charge. The odd of this happening are very small. Arizona has some of the toughest DUI laws in the United States. At the end of the day, I needed someone who was passionate and had made a career of defending DUI cases. I needed Mark Dubiel. There is no one else I would recommend to deal with a DUI case PERIOD especially in Arizona.
