I was born in upstate New York and have been living in Florida for the past twenty-two years, having moved here to attend St. Thomas University Law School in Miami.  When I am not busy working on behalf of my clients I enjoy spending time with my family enjoying everything Florida has to offer, from the theme parks to the beaches to the parks and springs.

This review is from a person who hired this attorney.
| Hired Attorney
Did a great job
Mr. Brennan was appointed to represent me in a case where I was completely innocent. I was in jail but he kept coming to see me to keep me updated as to the case. He was albe to give the state enough evidence to show I was not guilty and they finally dropped the case.

Extremely helpful and honest lawyer
My father and I hired Gregg after we were charged with a hunting violation by an FWC officer. Gregg answered all of our questions we had about the charges and kept us informed through all the court proceedings. He pushed that state until they dropped the charges they had against us. While we hope to not be in a situation like this again if we do we would not hesitate to hire Gregg again.

Definition of Proffesional
Gregg was hired to research and process a petition. At all times from introduction to closing my case he was all of the things you would want from council. Trust worthy - Everything he said was to the point, and to the law. He made no promises he did not keep. Responsive - From our initial meeting he researched my case to the full and informed me of my options. Knowledgeable - My case was not something that Gregg had much experience with. However, he he hit the books, read up on the laws concerning my petition and made himself familiar with how my case needed to be addressed. Kept me informed - From the beginning to close of my case Gregg made it a priority to inform me of what he would be doing and any changes to my case. I fully endorse Mr. Brennan to anyone seeking a lawyer.

I'm impressed with this attorney.
I found Mr. Brennan for a neighbor that faced a ridiculous battery charge. Mr Brennan kept my neighbor informed at all times. I was present at the meetings because my neighbor wanted an extra set of "ears" regarding everything that was happening. I found Mr. Brennan to be courteous, professional, and likeable. I have to commend the prosecutor, also. I felt he was fair. At the sounding docket Mr Brennan wa able to get my neighbor into an early intervention type progrram despite objections by the "victim". The case was frivolous IMHO, and Mr Brennan was able to convince the prosecutor that to go forward was a waste of the state's time and money.

Good attorney who helped my brother out alot.
My brother got Mr. Gregg to defend him against some serious felony charges. The state was gonna try to put him away for life times two, but Mr. Gregg got one case dismissed and the other he got my brother a three year prison sentence. No small amount of time, but better than life. My brother is in prison but is getting out soon and that's thanks to Mr. Gregg. Hope I don't need a lawyer but if I do I know who I will call.
