“I thought I was dead to rights. I blew a .26 on the breath test which was over 3 times the legal limit. Somehow, James got the DA to agree to keep it out of evidence against me at trial. Plus, the civilian caller who followed me also showed up at trial and took the stand but James pointed out inconsistencies in his testimony. There was even a bad video but James totally turned that around on them.”

“James is totally together. He had the DA scrambling at trial. He’s a rock star! I give him 5 stars.” -Joey

You kept everything on a positive note giving us comfort that we were represented by a knowledgable and professional law firm. Despite her accident and failed breath test, attorney Dunn achieved a dismissal of all the charges against her. Kudos for your efforts, compassion and a job well “Dunn.” -Frank C.

“Attorney Dunn was thoroughly professional from start to finish. I was worried about how it would turn out but he put me at ease. He did a great job at jury trial and dramatically caught the trooper in not just one but two lies. The jury didn’t like that at all! They found me not guilty of OUI and not guilty of reckless driving. I couldn’t recommend him more highly.”

“Attorney Dunn kept me at ease throughout. I couldn’t ask for a better result.” -Chris

"I can't thank attorney James Dunn enough. He always listened and understood things from my perspective. He always responded quickly and answered all my questions.

At trial, he kept the breath test out and won a NOT GUILTY!"
