You want Jim Dunn on your side!
My first DUI lawyer for the same case and who was highly recommended, cost twice as much as Jim Dunn, could not close the case like Jim did, was unavailable to be reached on his personal cell (had to go through his secretary all the time), and was not as personable as Jim Dunn. And on the contrary, Jim was easy to reach and even called me several times to check in; also, my first lawyer would not do a thing unless you read through and signed page after page of legal jargon to "prove" why he was worth the outrageous retainer. Jim Dunn didn't even charge me until the case was settled. Also, my first lawyer was confused as to what the judge ruled, and this led to a misunderstanding and a bench warrant that led to my arrest two years after the DUI. Jim Dunn had a VERY good understanding of the law and was able to explain every possible ruling before our court date and clean up the mess my first lawyer helped to make. Jim Dunn is trustworthy, reliable, personable, honest, and fair, especially when it comes to his costs. Take it from me, he is HALF the cost of these "hot shots," but gets twice as much done. He came to my jail cell in Redwood City on a Sunday night to help get me out that following Monday. My family was unable to reach my previous lawyer whose "care" I was still under. Jim wrote up a transfer, got me a trial the next day, and got my bench warrant dropped within one day! The legal and justice systems are a nightmare, you don't want to get caught up with them, but if you do, you want Jim Dunn on your side!
