Great Lawyer

I went to Matt after the first attorney I hired had worked my case for months. The end result was an offer from the state that would cause me to lose my license forever. I talked with Matt and after he reviewed the case he thought there were still arguments to pursue. I took a chance, turned down th...e offer and hired Matt. He filed many motions and kept at it. In the end, the judge dismissed all charges. Matt knows the DUI laws and I trust he will do everything he can for every client. He was responsive and realistic throughout. He never promised miracles. He knows the law and that's what you need in a lawyer.

"I highly endorse Mr. Olszewski. There are not a lot (maybe none) of DUI attorneys in Orlando that can say that they literally wrote the book on DUI. Matt is a great lawyer with a wealth of knowledge. As a former prosecutor I can say that he uses his knowledge and personality to effectively negotiate and advocate for his clients. I highly endorse him for your DUI defense. You'd be lucky to have him in your corner."

"I have known Matt since he started practicing at the Office of the State Attorney a number of years ago. After leaving the Office of the State Attorney Matt continued his work for the State of Florida by traveling around the state both training prosecutors how to proerly prosecute DUI's and training law enforcement in how to properly investigate DUI's. Suffice to say this has provided him a wealth of experience and perspective in his role as a criminal defense attorney. Matt's reputation as a top tier DUI defense attorney has been well establisehed over the last several years. I would whole-heartedly recommend him to anyone charged with such an offense."
