John C. Martin is a partner at Sugar, Felsenthal, Grais & Helsinger LLP.  John’s  law practice is devoted to providing representation and counsel in complex business disputes, including contractual, fiduciary, and attorney professional responsibility matters. He has served as principal counsel in multi-million dollar commercial litigation, including opposing multistate class and shareholder litigation and the defense of direct and derivative claims against corporate and ERISA fiduciaries.

John’s clients range from individuals and small businesses to multinational corporations, and he represents both plaintiffs and defendants in a wide variety of commercial disputes, including corporate governance suits, trust litigation, and matters arising out of lending and other financial relationships. He has extensive trial and appellate experience before the State and Federal courts in Chicago, and frequently collaborates with other firms as local counsel.  For every client, in every matter, John takes pride in using his experience to find solutions that are both creative and cost-effective, working with (and listening to) his clients to identify the battles that need to be fought and fight them from the best positions possible.

John’s practice also extends to attorney professional responsibility matters.  He represents and advises both attorneys and clients in connection with professional responsibility matters and fee disputes.  He is an active member of both the American Bar Association Section of Litigation’s Ethics and Professionalism Committee (which he co-chaired from 2010-2013) and the Chicago Bar Association’s Professional Responsibility and Professional Fees Committees (which he chaired during the 2015-2016 bar years). He also served as a member of the ABA Ethics 20/20’s Working Group on Alternative Litigation Finance. He has spoken and published extensively on issues relating to legal ethics and attorney professional responsibilities, including recent presentations on attorney obligations relating to fees, attorney’s liens, advertising, and financing.

Prior to entering private practice, John clerked for the Honorable Suzanne B. Conlon of the U.S. District Court for the Northern District of Illinois.
