"Mark is one of the most intelligent attorneys I have worked with, he has the ability to understand and dissect complex legal issues and a practical mindset when dealing with clients focused on the bottom line."
"Mark and I defended our client's respective common trademark interests in litigation in the U.S. District Court for the Southern District of New York in 2006-09. Mark is professional and knowledgeable."
"I have worked with Mark for seven years, both in private practice and now as General Counsel for a pharmaceutical company that is a purchaser of legal services. In private practice, I know Mark to be a level-headed, solution-driven attorney. As company counsel, I have hired Mark to handle several complex intellectual property law matters, and sought his counsel on issues important to the Company. I, and the company's principals, have been very happy with Mark's work, the resolution of the matters, and the soundness of his counsel. I also know of no other attorney as adept in obtaining insurance coverage where others have given up. Without reservation, I can endorse Mark."
"I endorse this lawyer's work. I have seen his work in patent and trademark litigation cases for several years. Mark is an outstanding lawyer by any standard."
