Mark Seitelman is one of New York's best lawyers and I will return to him again should I have future needs for legal representation. Mark handled a case for me which involved negotiating with several third-parties which he handled seamlessly. Mark did a superb job of negotiating and he also kept me informed of the progress toward resolution along the way. I highly recommend Mark for his competence as an attorney, his true professionalism and his dedication to handling legal matters with care, concern and skill. In addition, Mark is very responsive, always answering my questions in a timely manner and returning my calls.
