DM Cantor and Jason specifically, was an ally from start to finish! Put their card in your wallet now and keep it on hand in the event that you ever need an attorney. Complete professionalism, tact, facts and results. Let them do their job! They are the best situated to bring the outcome you seek. My case was dismissed by the prosecution a week before trial!

I recently went to trial for suspicion of DUI. I was faced with 6-15 years in state prison because of past offenses. My lawyer, Jason, put in 5 motions to dismiss or suppress before going to trial. During trial he overcame over 70 objections that were overruled and the jury came back with a decision of not guilty! My experience with Jason has been nothing but positive. I highly recommend Jason as a fantastic lawyer and a great person as well!

Knowledge of the law and how to fairly and appropriately apply it is crucial to winning your case. Jason Karpel not only did this, he was able to use his knowledge and have my charge dismissed at trial. If you’re looking for someone to provide you with fair, open and honest, timely communication, and to take your case as seriously as you do then don’t hesitate to call to Jason and DM Cantor. I am glad I did.
