In Fort Pierce, Port St. Lucie, Stuart and Vero Beach, Criminal lawyers know "DUI's", "Drug Possession", "Drug Trafficking", "Prescription Fraud", "Unjust Battery", and "Internet Crime" cases dominate the headlines. If you are charged with these or any other crimes, you must find the most talented, experienced team of legal professionals to obtain optimum results.

The practice of criminal law has evolved into discreet and specialized areas, including DUI, Internet Crime, Drug Possession and asportation cases, embezzlement, homicide, etc., -----with the developing tendency of Florida's legislature to criminalize all manner of proscribed conduct--- the list grows longer each year.  Criminal cases routinely require astute counsel to assemble a  winning defense team, which may include Physicians, Psychologists, Accountants, Laboratory Analysts, Arson Investigators---- this list expands each year as well.  Knowing , and being able to access, the right experts and consultants, and being able to work effectively with them, can  and does make the difference between winning and losing your case.

Highly recommend
Kirschner and staff has been amazing. They provided clear and specific communication, clear expectations and timely follow up. This was not normal experience for us and they understood that. They were always available to answer or follow up via phone or email. During a very stressful situation I felt confident with Mr. Kirschner representing us. He was very easy to work with and he went beyond what he was hired to do for my family.

Criminal Defense Case with Jay
Throughout the entire process, Jay did a good job making me feel informed and comfortable, considering the potential consequences I was facing. I would absolutely recommend him to any person who finds themselves needing legal counsel in this county. Jay and his associates really went to bat for me, and I couldn't be more thankful. Humbly and Sincerely, Cam

Outstanding attorney and team of professionals
I reached out to Mr. Kirschner about 10 months ago. I live in Kansas and my ex husband lives in Florida and I needed to take my ex-husband back to court to amend child support. Mr. Kirschner and his staff provided excellent communication, detailed information of what they needed me to provide and was able to resolve the issue without me or my ex-husband having to go to court. They are a very knowledged staff, very helpful and in my opinion very entertaining I truly enjoyed the experience as in most cases dealing with legal issues with child support is not. I appreciate all they have done and will use Mr. Kirchner and his staff in the future and would highly recommend them to anyone.

The best, honest, sincere and thorough
Well, once again I had the need to contact Mr. kirshner with my son's heroin legal problems. He was honest, upfront, kind and honest. I have used Mr. Kirshner twice before where he was able to plea the case in my son's best interest. If I had not known better, I would have thought he was magic. As of this writing Mr. kirshner will have some more magic to perform. He is simply the best. Second to none.

Best Criminal Defense Lawyer in FL
Jonathan Jay Kirschner and his legal team represented my wife in two criminal defense cases in Hillsborough County (Tampa). Him and his legal team were extremely versed in the legal process for these offenses and were also well equipped to guide us through the difficult process with the Hillsborough County Circuit Court (notoriously difficult to deal with). They were able to get one offense expunged after time and represent my wife in the second case as we moved out of state. They are very professional and a joy to work with. I am very please in our decision to hire their representation and would recommend them to anyone no matter the size/difficulty of the offense or case.

Honest, Empathetic, Professional, and Experienced Attorney-truly the Best!
After consulting with other attorneys, Jay Kirschner stood out as the most empathetic, honest, and professional that I needed on my side. After being falsely accused on a battery charge, I came to the best attorney that was not afraid to investigate and speak the truth on my behalf and defense before the State and the City of Port St. Lucie police department bringing about a justly non-guilty verdict. Jay Kirschner and his staff including Collette and Kim truly cared for me and the suffering this false accusation brought upon my family and myself. They all took our case personal and we felt supported as if we were family. Jay Kirschner and his staff were very patient, kind, honest, empathetic, and dedicated extra time explaining to me the judicial system, the laws, and really listening to my case. Look no further...if you want the best attorney and team, Jay Kirschner gets the five stars and beyond!!

An attorney to trust during difficult times
Jay Kirschner is an experienced, knowledgeable and creative attorney. His responsiveness, intelligence and sense of humor were helpful during very challenging circumstances. Mr. Kirschner and his staff were caring, professional and available when needed. He was recommended to me by a friend who said I needed a strong advocate. His performance exceeded my expectations.

Of the many lawyers that I have dealt with over the years, Jay Kirschner stands out as being the best! I was looking for an attorney in St. Lucie County on this web sight. Jay had the credentials and the experience. During our initial conversation, I felt that he knew what he was doing and would do his best. He was not full of himself or talking to me condecendingly; we became friends immediately. He knew the charges. He knew the law. We discussed all the weaknesses of the prosecutor's case at length. Jay had been working in St. Lucie County for nearly 30 years so he knew most of the prosecutors and judges. He told me exactly how the case would be prosecuted and that he would initially try to get the charges dropped. Due to Jay's diligence, the charges were dropped right out of the gate and life went back to normal. In St. Lucie County, you can count on Jay Kirschner to give you the best representation avilable. He's the Man!

I was desperate. I had been arrested and charged in St. Lucie County (2 felony, 2 misdemeanor). I do not live there but wanted local representation. From this site I found Mr. Kirschner. I called and explained my situation, even during the initial call he took his time with me and answered any questions. I set an appointment to meet him. His assistant Colette, was fantastic. Mr. Kirschner being very personable and patient spent hours with me, discussing things and this was into the early evening of a Friday. Long story short, Mr. Kirschner was able to get all my charges DROPPED. I could not of dreamed of a better result or a more well rounded, qualified, expert attorney. I know personally how difficult it is to KNOW if you have the right attorney. I promise you, if you are seeking legal counsel and RESULTS, NOT calling Mr. Kirschner would be a huge mistake.

Family Law
Jay Kirschner is an excellent Advocate. His knowledge and professionalism are unmatched. He helped me through my initial divorce proceedings and through many subsequent motions and mediations over a twelve-year period. It was impressive to observe Jay in the courtroom environment. His preparation and attention to detail in all things was fantastic. He also has a great capacity to listen to and understand the needs of his client. In my opinion, Jay is truly a credit to the legal profession.

I can not thank, nor recommend Mr. Kirschner enough!! I was informed he was one of the best by friends and associates, but I now know he indeed is. He helped me during a very difficult trial when the "odds" were not in my favor. He prepared and collected information, and thoroughly presented the facts to show my concerns and gain an INCREDIBLE outcome. I could not have asked for a better ending. It would not have been possible if Mr. Kirschner and his office had not stood beside me, personally and professionally. I will never be able to express my appreciation enough.

Mr. Kirschner and his staff are extremely professional. I have been a client for the last three years and have been very pleased with the work they have done on my behalf. I have recommended Mr. Kirschner's services to friends and family, and would most certainly hire him again in the future if the need arises.

Excellent Attorney
I had a very litigious, emotionally charged, and complex family law case. Mr. Kirschner is extremely skilled and well versed in the law. He kept me updated on a regular basis and explained his strategy and discussed all options with me. His fees were very reasonable. If you need a conscientious, skilled, extremely knowledgeable attorney, then Mr. Kirschner is the attorney you need to hire.

Phenomenal Caring Brilliant Criminal Defense Attormey (not oxeymoron)
Jay stepped into a disorganized pending trial and made all the difference in the outcome (a 29 minute not guilty on sex offense).He was thoughtful, perceptive, organized, and able to rescue the case from a certain conviction to a successful conclusion. He was able to think outside the box, dedicated to tracking down trailing details, and dogged in his depositions for needed information. His overall strategic decision making during the course of the trial allowed the Judge to accept evidence whereas prior attempts had been unsuccessful. Thus he not only managed the client and his very emotional family but he also skillfully managed the Judge and the jury. His style with the jury matched what they needed and he was in control the entire time. Without his brilliance, common sense, and dedicated determination the verdict would have condemned this client to life in prison and registration as a sex offender. The complainant was six years old and the motivation from the family was persistent. The prosecutor was skilled and experienced and graciously admitted defeat. Jay should be the first one on your list to call.

Hero Lawyer
I was working as a trial consultant for a child sexual abuse case with a lawyer that just didn't understand how to defend it. At a point of crisis with the uninformed & unwilling to learn lawyer, Jay was brought in as co-counsel. As I expected, Jay took charge of the issues the other lawyer did not understand. Jay, myself and our expert all worked together as a team and enjoyed a stunning 29 minute deliberated "Not Guilty" verdict. Working with lawyers all around the country, Jay is extremely competent and detail oriented. Without hesitation, I would recommend Jonathan Jay Kirschner again and again!

Truly Masterful Attorney
Mr. Kirschner was attentive--always keeping me "in the loop" during the pretrial period. He even gave me his cell phone number in case I got nervous or had questions after hours. During the trial he was amazing in the court room, reminding me that Perry Mason still exists!

Review of Jay Kirschner
EXCELLENT, above reproach. I have had the unfortunate opportunity of employing many lawyers for my son's heroin addiction criminal actions and Mr. Kirschner was above reproach. Mr.Kirschner was always available by phone or email, he immediately responded to any questions or requests, went above and beyond in representing my son in two different cases on two different occasions, one of them out of the county where he is employed and I had been so satisfied with his in county performance that I again contacted him to represent my son, even though I was told over and over I needed a local attorney. Mr. Kirschner takes a personal interest in his clients. While my son was in jail, he also had the opportunity to talk to other inmates who utilized Mr. Kirschner and they too highly recommended him to my son.

Honesty, Integrity and a dose of Humanity
Mr. Kirschner is one of those very few attorneys who removes the intimidation of the legal system from the equation. His legal knowledge is complimented by his communication skills. The importance of identifying and retaining a quality lawyer crucial to any legal action. Too many lawyers are removed and detached from the their client and the case. Mr. Kirschner and his staff display a level of empathy that is beyond reproach. Specifically, I would have to make note of his Paralegal Juanita Dunn. She is the point person and always makes the client feel at ease and represented by the firm. Look no further than Jonathan Jay Kirschner. He will fight for you but he will also be honest when it is difficult to hear the truth.

"Let's face it. Lawyers in Florida are a dime a dozen. Cheap polyester suits, Big promises that always seem to fall short. How can you tell you're associating yourself with the right legal representative? Take a look at what his associates say. I've known Mr. Kirschner for over ten years, and have had the pleasure of working with him, and even working against him as a former prosecutor. Bottom line is the guy's an old school pro. Much smarter than the majority of the legal community around him, and with the respect of everyone in the courthouse from judges down to the cleaning staff. If my own mother were arrested, his office is my first stop. I heartily endorse this lawyer."

He has common sense and is able to have successful discussions with prosecutors prior to proceeding to a jury trial. I've retained him before and would not hesitate to retain him again.
