Mark’s practice focuses on enterprise IT and outsourcing deals.

In 2015, The Best Lawyers in America announced that Mark was named the “Lawyer of the Year” for Technology Law in New York City for 2016.  Each year, Best Lawyers names a single lawyer in each specialty in each community as a “Lawyer of the Year.” Those honored have received particularly outstanding ratings in the surveys by earning a high level of respect among their peers for their abilities, professionalism and integrity.

Mark has appeared on "The Best Lawyers in America" list since 2003. Since Best Lawyers bases its choices on a confidential peer-review survey in which over 25,000 leading attorneys cast about two million votes on the legal abilities of other lawyers in their specialties, and because lawyers are not allowed to pay a listing fee, inclusion in Best Lawyers is considered a singular honor. Corporate Counsel magazine has called Best Lawyers “the most respected referral list of attorneys in practice.”

Further, his peers also selected Mark to be on the 2015 New York Super Lawyers list. Super Lawyers are those who were in top 5% of the vote in a state.

Since the mid-1990’s, Mark has spoken to hundreds of groups domestically and internationally including multiple appearances at Georgetown University Law Center’s Advanced Computer Law Institute, COMDEX in Las Vegas, and seminars offered by the American Corporate Counsel Association and the Practicing Law Institute.  He has also been a guest on many television and radio shows including CNBC’s “Closing Bell” and ABC’s “Nightline.”

Mark authored the book Technology Law - What Every Business (and Business-Minded Person) Needs to Know.

Mark has served on the Board of Directors of the South Florida Technology Alliance, the Advisory Board of BNA’s Electronic Commerce & Law Newsletter, and the Board of Editors of “Internet Law and Strategy,” a publication of Law Journal Newsletters.
