Hire the best DUI attorney, Joe Lazzara. He is experienced, aggressive and his fees are reasonable. He fought for me and got my DUI dismissed. I would highly recommend Joe Lazzara.- Former Client

I hired Joseph A. Lazzara for my second DUI. I was scared because I screwed up. Joe Lazzara put my mind at ease and immediately began investigating the case. He found out that the officer was not properly certified and that the lab screwed up my blood test results. I thought for sure I would lose my driver's license for 2 years. He WON. We then went to trial and he tore apart the police officer and the expert from the lab. The jury came back not guilty in 30 minutes. Joseph Lazzara WON my criminal and DMV case. He saved my job and my family. I don't know what I would've done without him. I HIGHLY RECOMMEND JOSEPH A. LAZZARA AGAIN AND AGAIN.- Former Client

He fought for me the entire way and ultimately won my case at trial. The one thing I can say is he was very thorough and knew more about DUIs than even the police officer or DA. Pros: Knowledgeable and a Fighter Cons: NONE- Alicia
