THE BEST
Mr Ohalloran helped our son. He was facing some severe felony charges. I researched and saw his reviews and that he was a former prosecutor. He knows what he is doing. He had my son out of jail n one month with no probation The funny part is.....He didn’t even need to spend much time on the case because after we hired him ....he got to work immediately. He kept in touch with me and I would recommend him to anyone who is facing some jail time He got the job done with no drama and straight forward results Thank you Sean Londa Theriac

Told me how it was going to be, not what I wanted to hear.
Sean took the time to explain to me the details of my case, even before I hired him. He did not sugar-coat anything; he explained in detail the exact process and what to expect. During the course of my case, if I had a question, he was prompt in his answers, whether through the phone or email. Just had some minor issues with clerical errors on paperwork, but it was corrected immediately. Overall, Sean was very knowledgeable and understood the judicial process.

Generous, Knowledgeable, Prompt Call back
I was referred to Mr. O'Halloran by an excellent attorney in the area who I trust. Attorney O'Halloran provided me with details on how to handle getting my niece out of a sticky situation and he followed up with me. Even though it turned out we weren't able to hire him he answered more questions during the followup call. Quality, knowledgeable, caring attorney.

Simply the Best
It goes without saying a criminal charge is serious. When your reputation and future is on the line you need serious talent. Mr. O’Halloran is that! He gets the top award—not for acting, but performance. Don’t bother with other counsel. He is thorough, patient and well versed, not only in the law but opposing counsel and judges. Whereas he will lay out your case he will merely advise a direction based on the aforementioned skill set—not dictate a choice. Approachable, confident and all in on your behalf. When selecting a criminal defense lawyer there is only one choice; Sean O’Halloran.

5 STARS!
I was referred to Attorney O'Halloran by a friend when I found myself in bad situation. Attorney O'Halloran answered my calls personally and explained to me exactly what needed to be done and he did just that. He genuinely cared about my situation and cleared my name. As soon as I met with him I knew I was in good hands. Awesome Attorney!!

Beyond Thankful!
I called Attorney O'Halloran about my daughter being wrongly held responsible in a criminal case. Attorney O'Halloran immediately looked up the case, investigated and contacted who he needed to and was able to resolve the case. He saved my daughters opportunity to continue her career. Attorney O'Halloran is a very caring, personable Attorney and we will be forever grateful for him.

The MAN!!
C. Sean O'Halloran, by far one of Lee County top defensive attorneys. He's detailed oriented on how he approaches cases. Very proficient in his professional career. Would be first and probably only attorney I seek should I need one. Some cases can't be won in trial, but you'll get every penny worth from him by far.

Great Advice
Sean did a great job for me. His experience with the courts was very valuable and it was obvious that the Judge knew him and thought highly of him.

Very good
I am from ohio and ended up with a case there. I did an online consultation on a Sunday morning at 3am and Sean called me that afternoon. I gave him my situation and he explained my options. He got the job done for me and he is a very good lawyer. I hope that I never end up in trouble in Florida again. I would use him again if did.

HANDS DOWN THE BEST
I had a minor charged with a misdemeanor. Sean was there explaining everything from the beginning to the end, making everything simple. The best word to describe Sean is "GENUINE!" Definitely the attorney you want on your side, with out a doubt. For the best representation call Sean.

Trust Sean
I found myself in some serious trouble facing a felony that would have sent me to prison for a number of years. I went to Sean for help. He is a very straightforward and will tell you like it is. He will not judge you. He is very aggressive when it comes to your defense. He also has professional relationships with most of the prosecutors. This is VERY important. He knows how to talk to them to get you the best outcome possible. You should take this into account when you hire a defense attorney. Relationships have a huge impact in the criminal defense world. Trust me on this. He also returns calls promptly and his staff is great. To say I recommend him is an understatement. I put my life in his hands. He worked hard for me and was able to get me a good outcome. If you find yourself needing a criminal defense attorney call Sean. I wish you the best in your case.

Sean O'Halloran is a rock star - - - my go-to guy.
I am a lawyer myself, and I was referred to Sean by a lawyer friend. Sean helped us with a misdemeanor juvenile charge for my teenage son, and then also a serious car crash case. Results --- couldn't have been any better, and even better than Sean had prepared us for. Fantastic, no-nonsense lawyer. My new go-to guy. Strongly recommended.

Great attorney who cares about his clients.
Recently relocated and purchased a home in FL. Early retirement was going as planned until a life altering event as I was charged with DUI. What a humiliating and horrible experience. I was refered to Attorney Sean O'Halloran by an attorney friend of mine in the area. He advised if I want the best I should contact Sean. After speaking with then meeting Sean, he developed an coherent and actionable plan. Sean first filed for a hearing with the Dept of Safety. Though his skill and a bit of luck he actually got my regular drivers licence reinstated. Over a period of time and Sean's in depth research and documentation we were able to reach an agreement with the prosecutor, avoid trial and retain my licence was with some restrictions. I did have to pay a large fine, attend classes, and received a serious ticket but was not convicted of a DUI. Sean is a true professional, kept me personally informed, always returned my phone calls and pocesses superior legal acumen in his field of practice. High marks all around including that he genuinely cares. Sean is the simply best!

High Marks
Sean was extremely helpful from the initial consultation to the resolution of my matter. Straightforward with potential outcomes, fought strong to avoid having to go in front of the judge and made helpful suggestions about the direction that would best serve me. Followed up and resolved my complicated case in a way that appeared effortless, eventhough I know it was more work than he suggested. I would highly recommend him to anyone that needs confident and knowledgeable representation.

Exemplary DUI Defense Attorney
Our Sons life was turned upside down last December when he was arrested and charged with a DUI. He lost his position in law enforcement the next day. He had never been in trouble before and needless to say our family was in turmoil. An attorney family friend recommended Mr. O'Halloran as the preeminent DUI attorney in Lee County. Mr. O'Halloran was able to get the charges dismissed against all odds. Our Son is now continuing with his law enforcement career. We cannot say enough about how pleased we are with the representation afforded us by Mr. O'Halloran. He was always available to talk to us either in person or by phone. He took the time to listen to our concerns and to explain in detail what strategy he was taking and what progress was being made in our case. He demonstrated the highest level of experience, expertise and the relationships needed to provide us with the best possible outcome given the circumstances. We highly recommend Mr. O'Halloran for DUI criminal defense.

Sean O'Halloran and his associates and staff are outstanding in their performance and the results they accomplish. Mr. O'Halloran went to bat for me in an extremly time-sensitive and sticky situation and negotiated a resolution better than any other attorney in our area could have hoped to achieve. I very highly recommend Mr. O'Halloran.
