For more than three decades, Mark S. Gottlieb has provided business valuation, forensic accounting, and economic damages analysis to attorneys navigating complex financial disputes. As the founder and practice leader of MSG, he was selected by Forbes as one of the Top 100 CPAs in the country in Business Valuation. His practice is built entirely around litigation support, and he is personally involved in every engagement the firm undertakes.
Mark’s casework spans shareholder disputes, partnership dissolutions, post-acquisition conflicts, breach-of-fiduciary-duty claims, and high-stakes matrimonial actions. On the valuation side, he appraises closely held businesses across a wide range of industries, tailored to the specific circumstances of each dispute. On the forensic side, he leads investigations involving alleged asset misappropriation, unreported income, financial statement manipulation, and corporate record-keeping irregularities. His forensic process frequently identifies anomalies in business records and the application of Generally Accepted Accounting Principles (GAAP) that inform litigation strategy.
Mark has been a testifying expert witness throughout the country in federal and state courts, arbitration panels, and mediations. In addition to his work as a retained expert, he has been appointed by courts to serve as a neutral financial expert in contested proceedings: a designation that reflects the confidence judges place in the independence and rigor of his analysis.
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.
