  • Lawrence James Fredella

    I endorse this lawyer with the highest ranking I can give him. I highly recommend Justin Heiferman to handle cases in the following fields of law: employment law, immigration law, and criminal defense. I have known Mr. Heiferman for 15 years now. He has been a practicing attorney in both New York and New Jersey for 10 years since 2005. I am familiar with his work since he was an Assistant D.A. in Nassau County where he worked from 2006-2010 where he handled complex economic fraud crimes. During that time period I was able to observe him in court and to see his work product as well. He is an excellent attorney, knows the law well, and is extremely responsive and courteous to his clients, going the extra mile for them because he truly cares about every case he handles. You will get all the attention you need with him as your attorney. You will also get the best result you can get with him by your side.
