Mark E. Segall, Esq. is widely recognized as one of the country’s leading experts on the evaluation of litigation risk, settlement strategy and mediation of cases involving financial services firms. He has been an active speaker at industry and litigation conferences and a participant in court-appointed focus groups. Since joining the JAMS Financial Markets Group in August 2010, Mr. Segall has been engaged in a variety of complex matters in which he has brought to bear the extensive experience he gained managing litigation and difficult, high-profile matters both domestically and world-wide during his 20-year tenure at JPMorgan Chase (JPMC) and its predecessor firms. 

Mr. Segall possesses a thorough understanding of the complex issues involved in resolving financial industry disputes, the result of having served as JPMC’s Head of Litigation, Senior Vice President, and Associate General Counsel for the past seven years. The litigation spanned JPMC’s six businesses -- Investment Banking, Retail Financial Services, Card Services, Commercial Banking, Treasury & Security Services, and Asset Management. Most of the important cases brought against JPMC involved claims under the securities laws as did countless more mundane matters. Securities claims were asserted in both litigation and arbitration, and many of these cases were resolved as a result of successful mediations.  Mr. Segall negotiated with a wide range of institutional litigants including hedge funds, insurance companies, public pension funds, other investment banking firms,  real estate firms, trustees and creditors’ committees in bankruptcies, and Fortune 500 companies.
