Great attorney!!!
He did everything he said he was going to do and did a great job at it!! Very personable guy but puts his game face on and very stern in the courtroom. He even talked to my teenage son afterwards and gave him some personal advice to keep him out of trouble. It was different than coming from Dad.

Outstanding trial lawyer
We were so lucky to have found such an amazing lawyer. He worked long hours on our case. He fought for our son as a criminal lawyer. Without him, I don't believe we could have gotten the verdict we did. Not guilty. Not all cases are the same, but if you need an excellent trial lawyer, Jarrett Ambeau will fight for you.

Job well do e
I had a friend that was dealing with some good ole boys type of law enforcement, basically being accused of doing nothing illegal and the District Attorney for this area wanted him to plead guilty for something he didn't do. I sent him over to Jarrett because I know the type of man and lawyer he is and he would be able to resolve. After short time the case was dropped and charges removed, just like I knew would happen. Pick the right attorney for the job and actions will happen. Jarrett was the right man for this job. Thank you Mr. Ambeau.

Knowledgeable and helpful
Mr. Ambeau worked diligently on my defense for over three years for the cost he quoted me originally. Like other reviewers mentioned, there would be an additional cost had we gone to trial due to the extensive amount of additional work that trial preparations would require, but that was clearly communicated to me in the beginning. His rapport with other lawyers and the DA's office was an asset during discussions, getting them to both listen and understand my position and I believe was directly responsible for eventual leniency. I'm very satisfied with Mr. Ambeau's representation and would recommend him to anyone seeking professional council.

Great job
He has done an outstanding job helping my son and working hard to get him the best outcome. Though I'm not easy to deal with as a mother, he is very understanding and respectful. I have recommended him and will continue to hire myself if the time comes. Thank you for the work you have done for my son and I!!

Outstanding lawyer
Mr Ambeau represented me when I was wrongfully arrested and had the entire case dismissed. I would recommend him to anyone looking for legal representation in the Ascension or Baton Rouge areas.

The Last straw
I looked at a couple of these reviews and I would have never thought Jarrett would have a negative one. Jarrett took on a case for me that another attorney had been working on and milking for 2 years. His prices are fair and services are untouched. Just set up a consultation with him and your gut will tell you that he's awesome at what he does and he loves to argue and prove points. Super guy in and out of the courtroom. He's gonna fight tooth and nail for his clients and he won't lose without a fight.

Excellent Recommendation
I have recommended Mr. Ambeau to several close friends of mine with legal trouble after learning about a serious criminal charge he was able to get a client exonerated from. Anyone I know who has met with or retained him as an attorney has been satisfied with the either the advice or the legal representation he provided. I will continue to recommend him and I have no doubt he will continue to provide the excellent services his clients have grown to expect.

Unexpected turn in life
Attorney Jarrett Ambeau has a tough job and went out of his way on a Sunday , to consult with my husband who is currently incarcerated on criminal felony charges. Though there was not a whole lot to discuss during this meet, it goes to show, and gave us great hope that justice will prevail. During the darkest and most hopeless moments of this life changing event, we prayed as a family and God sent us Atty Ambeau. Thank you sir,- on behalf of Mr. J.D.C( Ascension parish jail), the Crisostomo family

Swapping out, Sell out
Jarrett has taken on to many hight profile cases and isn't properly staffed. His performance isn't what it used to be in the courtroom. Have you ever heard of the term swapping out ? Well this is what Jared has started doing. Letting the DA do whatever they want in the courtroom and not objecting. Then for his next client the DA will take it easy on them. This is a known fact that this goes on in the courtroom. Jarrett will probably be running for DA in a few years.

Response from Jarrett Ambeau April 18, 2022
This is anonymous for a reason. It's complete nonsense. At no time in my career, not one single time, have I "sold out" any client. Ever. Period. I've committed my life to service of my clients and will do whatever it takes, within the law, to get justice.

Paid in Full- for lies and broken promises
Mr Ambeau gave me a set price (which was paid up front) but advised (after several months) that he wanted to go to trial with my husband's case and this would be an additional 10k (which was also paid). He instructed me that if he did not go to trial, he would refund the money back. My husband did not go to trial and he refused to refund us the additional 10k that was paid. We paid for a couple "specialists" and was told that was included in the amount paid. He told me he used these specialists, but I have yet to see any documentation from one of "specialist". I asked for an itemized bill so I could see where the money was spent, nothing justifies the amount of money we paid this man. This was a living nightmare for my family. Mr Ambeau lied to me and my spouse (I had proof of this) but he did not budge. He lied to my husband and myself throughout the entire process. I would not recommend him to anyone for legal services. If you are looking for someone to work for you, be upfront and honest and justify the amount they have charged you, he is NOT THE ONE!!

Response from Jarrett Ambeau May 31, 2017
I am sorry that you feel as though we did not take care of you here at The Ambeau Law Firm; your feeling that we did not take care of you is not what we desire and indicates a certain kind of failure on our part, if only insofar as you walking away feeling like you were treated with anything other than the utmost respect and understanding. As this is an anonymous post, I am in a difficult position to address your assertions specifically without knowing who you are. None of the facts above match any case I have had in my office since opening 8 years ago. Obviously I could not actually treat anyone this way, keeping money that was not earned, and still be practicing law. If I can address any factual concerns I can be reached at my office at any time. In the end, I hope everything worked out for you and I wish you the best going forward.
