Greg Gatjanis is a Senior Policy Advisor at Fluet, bringing nearly four decades of distinguished service in U.S. and international security to the firm’s International Trade practice. He advises clients on complex matters involving financial sanctions, anti-money laundering compliance, international trade controls, and U.S. national security policy.

Drawing on his senior leadership experience across the U.S. Department of the Treasury, the White House, the U.S. Drug Enforcement Administration, and other federal agencies, Mr. Gatjanis has developed first-hand experience and insight that enable him to provide strategic guidance and solutions to clients navigating issues at the intersection of global business, sanctions, regulatory compliance, foreign policy, and national security considerations.

Prior to joining Fluet, he served for more than 12 years as Associate Director at the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC), where he led the Office of Global Targeting. In that capacity, he oversaw designation and delisting investigations across 45 sanctions programs, including those focused on Africa, China, Cuba, Iran, North Korea, Russia, Venezuela, digital assets, global narcotics trafficking, as well as human rights and corruption (under the Global Magnitsky framework). In total, Mr. oversaw the designation of more than 10,000 individuals and entities and the delisting of thousands more. He has consistently emphasized that while designations demonstrate the power of sanctions, delistings reflect their integrity and credibility.

Mr. Gatjanis also served nearly seven years on the White House National Security Council staff under Presidents George W. Bush and Barack Obama. As Director for Terrorism Finance, Counternarcotics, and Transnational Crime, he managed a portfolio spanning Western Hemisphere counterterrorism, financial crime, sanctions policy, and global arms trafficking. During his White House tenure, he authored President Obama’s 2011 Strategy to Combat Transnational Organized Crime and the 2010 Presidential Proclamation for the Day of Remembrance for Victims and Survivors of Terrorism.

Throughout his career, Mr. Gatjanis has delivered briefings and lectures at Harvard Law School, the Central Intelligence Agency, the National Security Agency, the University of Cambridge, and the George C. Marshall European Center for Security Studies.

In his free time, you can find him reading spy thrillers, writing, traveling with his wife and sons, playing basketball, and perfecting his “fadeaway” shot.
