Review Jason Seidman

Best attorney

Posted by

Let me start off by telling you Jason is not your typical lawyer liar. Jason is actually an attorney who cares. He puts effort in his work and also takes the time out to speak to you without saying you owe him $1000 for a phone call. I’ve dealt with a lot of attorneys in my life as far as getting retired from a city job, As far as getting Social Security disability and Worker’s Comp. They all deserved that title lawyer liar. Not Jason, he did my red flag trial , Why a malicious doctor And his 24 hour on-call bully Lawyer decided to make false claims to have my firearms taken under his new horrible unconstitutional red flag law. Of course Jason won my case and my stuff is back in the safe where it’s been for 10 years not bothering anyone, but just because of a bad review my stuff was taken in an instant unconstitutional law. Not only would I consider Jason a great attorney but I now consider Jason a friend and that is more important than any case, because people like Jason are hard to fine. I’m glad I found him and I am happy That he not only won my case but we caught the other attorney in many lies which now makes a countersuit more important to me. And also give me the ammunition I need for malicious prosecution counter suit. So everyone reading this if you need a great attorney with a great attitude and a heart of gold Jason is the right person. Most get a bad name because of them going to bed at night dreaming of $ I’m not having any compassion , Totally different when you hire Jason. I give Jason five stars and if I can give him 10 he would definitely get that much.

You are an absolute amazing lawyer.

Jason, thank you. Seriously, no words could ever express to you how much gratitude, respect, and appreciation I have for you. I hung up, and cried like a baby..not because of what happened but because you had my back that entire time and I would be sent off to prison if it wasn't for you. You don't look or treat me as a criminal and that means so much to me. I respect you to the fullest and never forget how hard you have fought for me for over a year. your amazing. I admire you so much. You have shown me what a real attorney really does, and always asked and made sure how I was doing, and trusted what I had to say to you, always. You made me feel worthy. Not only did you do your job incredibly, you took your time to sit, listen, and talk with me. Thank you for all your hard work and dedication, Jason. You are absolutely amazing.

Excellent

" I need a good Lawyer "! How many of us have had to make that dreadful call. Filled with anxiety and fear of the unknown we desperately reach out for someone to assure us everything will be OK. The receptionist said " you came to the right place we have Great Lawyers! " Your lawyer will be Jason Seidman. Our case was not an easy one as it involved extradition. Information that I needed and what to expect with many "what ifs" were fed back to me immediately by Nelly, Jason's assistant. This type of Spirit to Serve is rare. It meant a lot to me, someone cared. The big day " court day ", Jason demonstrated his real talent! Backing up his experience with the prosecutors and the Judge he was able to completely have my son cleared and freed in record time. Those of you that have gone through this experience can relate to how wonderful a feeling it is. So no need to just settle for just any legal representation when you can have the very best with Jason Seidman of the Jonathan Marshall Firm!

One of the best lawyers!

Posted by

Jason has been the only one I could come to in my 3-year long case. He has been there every step of the way ever since the beginning. It has been a scary 3 years and I had the possibility of going away to Prison for a long time. Jason got me the best solution possible in my situation. When choosing a lawyer at first it's hard to know whos right, but just know Jason will do his best and fight for you the whole way until the end. You won't regret hiring him!

Went Above and Beyond!!!

Mr. Seidman helped with my matter in a very professional way. He was very informative, knowledgeable and guided me through the process. He was very patient with me and promptly responded to my e-mails and phone calls. I would certainly recommend his services to anyone who needs his area of expertise. Thanks Jason!

Thank You Jason, Thank you Brett, for fighting my legal battle. I made a mistake that you were able to correct. This mistake could have destroyed my career or worse put me behind bars. Jason believed in me, he was able to separate the meat from the bones and he never gave up on me or my case. I was found not guilty and innocent in the court of law. Thank you Jason! I recommend you to my friends and family.

Extremely thorough! Amended my case from a felony to an ordinance!

Posted by

I was referred to Jason through an amazing lawyer I know in Miami. Jason was extremely detail oriented and emotionally involved in the case. He was quick to respond and helped explain everything throughout the process. Jason got my case brought down from an Assault and Robbery to a Disorderly Conduct. I ended up just having to pay a fine for a charge that carries a max of around 10 years. I would recommend Jason to anybody that is looking for legal representation in Middlesex County. Can’t thank him enough!!

Jonathan Marshall, Criminal defense Attorney on Aug 10, 2016
Relationship: Opposing Counsel on matter

I endorse this lawyer. Jason was a prosecutor in Middlesex County and I had several cases against him over the years. I was extremely impressed with his knowledge, skill and dedication. I knew this would translate well as a defense attorney and offered him a job.

Leon Matchin, Criminal defense Attorney on Aug 9, 2016
Relationship: Opposing Counsel on matter

I endorse this lawyer. Jason is a former prosecutor and we worked together on cases which he prosecuted and I defended. In light of my experiences with Jason I know that he is smart and tough and does a great job for his clients like he did for the State.

Douglas Herring, Criminal defense Attorney on Aug 8, 2016
Relationship: Worked together on matter

I have known Jason Seidman for several years. He was a tough, knowledgeable, and extremely skilled prosecutor. He knows the law and every person in the Court system and Prosecutor’s office. He knows all the police and detectives. He is a extremely skilled trial attorney and an expert on criminal law. I highly endorse Jason Seidman.

Michael Allongo, Criminal defense Attorney on Aug 8, 2016
Relationship: Fellow lawyer in community

I have known Jason for five years and worked on various matters with him during that time. He is knowledgeable, competent, and, when necessary, aggressive. I wholeheartedly endorse him as an attorney without hesitation or reservation.

Matthew Dorry, Criminal defense Attorney on Aug 8, 2016
Relationship: Co-worker

I endorse this lawyer. When I joined the firm, Mr. Seidman was welcoming in discussing our cases and potential arguments for our clients. Our discussions prove to me his experience and confidence in advocating vigorously on behalf of our clients.

William Fay, Criminal defense Attorney on Jul 25, 2016
Relationship: Co-worker

I have come across a multitude of attorneys in my time practicing the law. However, I would be hard-pressed to name a single one who is more intelligent, astute, and kind-hearted as Jason Seidman. He truly is a student-of-the-law. If Mr. Seidman is handling your matters, you can be assured that you are in competent and caring hands.

William Proetta, Criminal defense Attorney on Jun 27, 2016
Relationship: Co-worker

I strongly endorse this attorney! This guy continues to impress me day in and day out with his hustle, dedication and knowledge of the law. Jay is the kind of guy who will never ask for a hand out - all of his accomplishments have been earned through shear determination and work ethic. He started his career as an intern at the Middlesex County Prosecutor's Office and soon gained the respect and recognition of the front office and he was hired as an Assistant Prosecutor. From there he quickly rose through the ranks to become the head of the drug task force. But what I find most impressive is how effectively he has transitioned into practicing criminal defense - something the vast majority of prosecutors are unable to do. Jay is one hell of a lawyer and an all around great guy and you would be lucky to have him represent you.

Keith Oliver, Criminal defense Attorney on Nov 10, 2015
Relationship: Opposing Counsel on matter

I endorse this lawyer. Jason joined our firm six months ago after being a Middlesex County Prosecutor for five years. He has taken all his training and experience that he gained as a prosecutor and now uses it to vigorously advocate on his clients behalf.
