Prior to joining Mayer Brown, Tim served in a variety of senior positions in the US Government for almost 12 years. He was the Chief of Staff in the Office of the US Trade Representative (USTR) from 2006 - 2009, where he oversaw implementation of US policy, strategy and negotiations involving all aspects of international trade and investment matters. He worked on a number of key issues including: climate change and trade; US and China relations; WTO negotiations and litigation; free trade agreement negotiations and implementation; and CFIUS decisions.

Before working for USTR, Tim spent more than five years at the Treasury Department from 2001 – 2006. He joined the Office of Legislative Affairs in 2001 as a Deputy to the Assistant Secretary for International Issues, where he was responsible for Treasury’s legislative strategy on issues including CFIUS, foreign exchange rate policy testimony, appropriations for US funding of the World Bank, and US participation in the International Monetary Fund. He later managed the Office of Legislative Affairs from 2002 - 2006 and assisted on all policy and personnel issues in the Office. This included leading Treasury nominees through the US Senate confirmation process, and legislative strategy on Treasury Intelligence and Anti-Terrorist Financing matters.

Tim also served on the Presidential Transition Team in 2000–2001 as a policy coordinator on export control and trade remedy policy, handling the Commerce Department’s Bureau of Export Administration (now called the Bureau of Industry and Security) and the International Trade Commission (ITC). Earlier in his career (1998-2000), Tim served as a professional staff member for international trade on the US Senate Finance Committee under Chairman William V. Roth (R-DE).
