He has over a decade of experience providing advice and counsel regarding the laws, regulations, policies, practices and politics of economic sanctions, export controls and other foreign policy and national security trade and investment controls. Adam advises clients domestically and abroad on international trade laws and policy, including economic sanctions authorities administered by the US Department of the Treasury’s Office of Foreign Assets Control (OFAC), the agency in charge of the implementation and enforcement of US economic sanctions.

Prior to joining private practice, Adam served with OFAC for over 12 years, including as the assistant director of the Office of Global Targeting’s Narcotics, Crime, Africa, and Western Hemisphere Division. During his tenure at OFAC, Adam was deeply involved in the development and implementation of OFAC’s sanctions programs, and many of OFAC’s most complex and high-profile sanction actions, including in the Iran, Venezuela, Russia/Ukraine, Narcotics, Cyber, and Cuba programs. He directed the teams responsible for OFAC’s management, development and implementation of designation strategies, designation investigations and delisting requests for numerous sanctions programs, including Transnational Criminal Organizations, Counter Narcotics, Venezuela, Nicaragua, Cuba, Global Magnitsky in the Western Hemisphere, Burma and nine Africa country programs.

Adam’s public service at OFAC also included several years of serving as an attorney-advisor in the Office of the Chief Counsel, Foreign Assets Control, where he provided OFAC with counsel and guidance on designation, delisting, regulatory, enforcement, compliance and licensing matters for virtually every sanctions program administered by OFAC, and was the primary author of multiple sanctions-related presidential executive orders. He also provided counsel to the Department of the Treasury’s senior leadership, the National Security Council, the Department of Justice, the Department of Commerce, the Department of State, and Congressional staff on OFAC-administered sanctions programs.
