Clients consistently return to engage Jason because of his track record of obtaining results that meet each client’s unique needs — as described in Chambers USA, “he is secure, confident and a skilled litigator. Jason is exactly the kind of partner a client wants by their side during a thorny litigation or arbitration — he’s always prepared, extremely disciplined in his thinking and calm in the heat of battle as well as being a consummate strategist.”

Jason is an experienced trial lawyer, with Chambers noting that he is “very capable in the courtroom.” He has tried cases to jury verdict or other decision in federal and state courts, regulatory tribunals and arbitrations around the country, including among others, the Southern District of New York, the District of Columbia, the Northern District of Illinois, the District of New Jersey, the Southern District of Ohio, and the Western District of Oklahoma; the Delaware Court of Chancery; state courts in California, Connecticut, Maryland and New York; and arbitration panels under the auspices of FINRA, NYSE, AAA, JAMS and others.

His clients include public and private companies, underwriters, lenders, professional services firms and their partners, corporate directors and other individuals in a variety of industries, including financial services, professional services, insurance, energy, defense, pharmaceuticals, manufacturing, real estate, supermarkets and telecommunications.

Jason represents these clients in securities, derivative, ERISA and RICO class actions, SEC, FINRA and stock exchange investigations and arbitrations, internal investigations, suits claiming breaches of fiduciary duty, insider trading or other misconduct by corporate directors, substantial financial instrument and other contract disputes, bankruptcy-related proceedings, and litigation arising from M&A or other transactions involving changes in or contests for corporate control in the Delaware Court of Chancery and elsewhere.

Jason is also a Lecturer in Law, focusing on corporate law issues involving governance, sustainability, compliance, and ethics, at the University of Pennsylvania Carey Law School, and is a member of the Advisory Board of Harvard Law School’s Program on Corporate Governance. A frequent speaker and author, he has contributed over 80 articles to the Harvard Law School Forum on Corporate Governance and Financial Regulation, and also published in, among others, Bloomberg, Thomson Reuters, The New York Law Journal and Columbia Law School’s Blue Sky Blog on Corporations and the Capital Markets.
