Mark S. Gottlieb, CPA/ABV/CFF, ASA, CVA, is one of the nation’s foremost experts in business valuation, forensic accounting, and litigation support. He serves on the AICPA Forensic and Valuation Services Executive Committee, one of the most prominent leadership bodies in the accounting profession, and chairs the Business Valuation & Litigation Services Committee of the New York State Society of Certified Public Accountants (NYCPA).
Named among America’s Top 100 Valuation CPAs by Forbes in 2025 and recognized on Forbes’ America’s Best-in-State CPAs list in 2026, Mark brings decades of experience and a rare depth of credentials to every engagement.
Mark is an adjunct professor at Fordham University School of Law, where he has taught since 2017. He previously held a faculty appointment at New York Law School. He lectures frequently to bar associations, professional organizations, and continuing legal education programs on business valuation, forensic accounting, and financial litigation. Mark’s analysis and commentary have been cited in national media outlets such as The New York Times, Inc. Magazine, The Hill, and the Daily Mail, and he has been interviewed on Bloomberg and WPIX News.
What distinguishes Mark from other practice leaders is the directness of his involvement. Unlike the national consulting firms, where senior professionals pitch the engagement and junior staff execute it, Mark works hands-on at every stage: scoping the assignment, analyzing the financial data, preparing the expert report, and presenting testimony. Attorneys who retain MSG get the expert they met in the initial consultation, not a delegate. That model has sustained the firm for over 35 years and has earned the trust of a referring attorney base that spans across the country.
