Mark was named to the inaugural Lawdragon “Leading Global Tax Lawyers” list, recognized as a “Bankruptcy Tax Specialist” by Turnarounds & Workouts magazine, and recognized for Tax and Nonprofit Organizations by Super Lawyers.

His experience in this area touched the entire life-cycle of an exempt organization, from formation to dissolution, and included a unique expertise relating to commercial activity and business ventures conducted by these organizations. Mark was co-chair of the Firm’s Not For Profit practice group, a long-term member of the Firm’s Pro Bono Committee, an integral part of the Firm’s annual Symposium on Not-For-Profit Governance, and served on a number of non-profit boards, including New Yorkers for Parks, The Jewish Education Project and Lawyers Alliance for New York. In 2014, Mark was chosen by the New York Law Journal as one of only 15 “Lawyers Who Lead by Example” in the pro bono category for his “outstanding record of providing crucial legal services to poor or nearly poor New Yorkers.”
