Jon Eisenberg is a partner in the firm’s Washington, D.C. office. He focuses on representing financial institutions and individuals in enforcement matters, litigation, and internal investigations.

Professional Background
After leaving the SEC’s Office of General Counsel, Mr. Eisenberg spent roughly half his career in private practice and half in senior in-house positions. He served as General Counsel for UBS Wealth Management Americas, where he headed the legal department responsible for regulatory relationships, litigation, and legal issues involving the broker-dealer and its affiliated bank. Before that, he was General Counsel for Merrill Lynch Global Markets & Investment Banking Litigation and Co-Head of Merrill Lynch Global Litigation, Employment, and Regulatory Affairs. At Merrill Lynch, Mr. Eisenberg helped bring to successful conclusions class actions involving Enron, the bursting of the Internet bubble, alleged manipulation of IPO prices, and execution practices involving Nasdaq market orders. He was a member of the team that developed Merrill Lynch’s successful strategy in the Supreme Court and appellate courts for preempting state law securities class actions, preempting federal antitrust actions involving securities-related activities, preventing so-called “scheme” liability, and establishing the standards for loss causation – decisions that have resulted in the dismissal of billions of dollars of claims. During more than sixteen years in private practice, Mr. Eisenberg has represented firms and individuals in class actions, government investigations, and arbitrations.
