David Metzner, Managing Partner
David Metzner has consulted for over 25 years on the federal nature of the American Government and the interplay between the states, Washington, DC, and foreign governments in the development of public policy. This has included national debates among the Republican and Democratic political parties, the regulation of the financial markets, trade policy, intellectual property and foreign policy.
Mr. Metzner co-founded the American Continental Group (ACG) in 1994. In this capacity, he has assisted corporate and non-profit organizations in understanding the development of public policy in general and complex financial regulatory events in particular.
In 2007, Mr. Metzner assumed the leadership of ACG Analytics, the firm’s analytical consultancy, which advises asset managers and corporate leaders on how public policy can affect their investment and management decisions.

Since the firm’s inception, he has supervised the publication of over 9000 pieces of written research and countless custom research assignments for clients. Additionally, he has led the organization of research trips to Athens on Grexit, London on Brexit, Berlin on EU macro and Washington on the Venezuela crisis, the GSEs and Puerto Rico. He is frequently asked to speak on the development and implementation of the Trump Administration’s domestic and foreign policies.
Mr. Metzner began his public policy career as the Director of Legislative Affairs for The Singer Company. He assisted the CEO and other senior executives in developing and advocating corporate positions on tax policy, international trade, and national security. During this period, he often spoke to corporate employees about the private sector’s role in policy development at the state, local, and federal levels of government.
In January 2009, Mr. Metzner completed his six-year Presidential appointment as Vice Chairman of the Board of Trustees of the Woodrow Wilson International Center for Scholars. In this role, he focused his efforts on strengthening the Center’s programming on Globalization, China and Latin America. He led the Board’s initiative in creating the Kissinger Institute on China-United States Relations. Congressman Lee Hamilton, the Wilson Center’s President, called this the “Center’s most important initiative in thirty years.” The Chinese Government has enthusiastically endorsed the Institute for its leadership in the two nations’ bi-lateral relations. He is a member of the Economic Club of Washington and the National Committee on US-China Relations. He has been recognized by Crain’s New York Business and Washington Life for his deep understanding of the developmental process of public policy in the United States.
Mr. Metzner earned a Bachelor of Arts in Economics from Boston University, a Master of Arts in Law and Diplomacy from the Fletcher School of Law and Diplomacy, and a Juris Doctor from the George Washington University National Law Center. While at Fletcher, he produced a highly regarded thesis on the role of the Vice President in Foreign Policy.
