Office Managing Partner


M&R’s White-Collar Defense & Investigations Practice Group represents corporations, boards of directors, executives, and other individuals around the globe in high-stakes matters relating to white-collar criminal defense, regulatory enforcement actions and investigations, and corporate internal investigations. We have extensive experience handling every aspect of such complex cross-border and domestic matters, which oftentimes involve multiple regulators, enforcement authorities and sometimes private actions.

Our white-collar attorneys—including decorated former federal prosecutors—call upon a full range of skills and resources from our other practice groups, allowing us to represent clients across multiple industries. On their behalf, we navigate all stages of the investigative and prosecutorial process in cases involving the U.S. Department of Justice, the Federal Bureau of Investigation, the Securities and Exchange Commission, the Federal Deposit Insurance Corporation, the Internal Revenue Service, the Federal Aviation Administration, the Environmental Protection Agency, the Department of Defense, the Commodity Futures Trading Commission, the Office of Foreign Assets Control, and various state attorney generals’ offices. From grand jury subpoenas and trials to appeals and post-verdict litigation, we’re exceptional advocates with extensive experience.

To reduce the impact of these actions on business, we also conduct thorough, reliable and cost-effective internal investigations, clearly defining their scope with our clients from the start to focus on key issues—all with an eye toward using the investigative record to persuade the government to decline prosecution or enforcement when appropriate.
