Christopher H. Casey is a first-chair trial lawyer who concentrates his practice in the areas of white-collar defense and criminal and civil antitrust litigation, and has particular experience with the healthcarepharmaceutical, financial services and food industries. Mr. Casey previously worked in the Associate Attorney General's Office of the United States Department of Justice, the Federal Trade Commission, and as an Assistant United States Attorney. Relying on his government experience, he regularly conducts internal investigations for his clients.

As a Deputy Associate Attorney General from 2014 to 2016, Mr. Casey advised top officials in the DOJ on the formulation and execution of policy in the areas of financial fraud, antitrust, tax and bankruptcy. Mr. Casey’s oversight responsibilities included the Antitrust Division, the Tax Division, and the United States Trustee Program.

He was one of two deputies to the Associate Attorney General—the Department’s third-highest ranking official—who supervised the Department’s cases against the world’s largest financial institutions for the fraudulent packaging and sale of Residential Mortgage-Backed Securities (RMBS).  In this role, he worked with the President’s Financial Fraud Enforcement Task Force and RMBS Working Group, as well as lawyers in the Department’s Civil Division and in U.S. Attorney's Offices throughout the country.  Those cases produced multibillion-dollar settlements with some of the world's largest financial institutions. He also worked with the leadership of the United States Trustee Program, the watchdog of the U.S. bankruptcy system, on investigations of mortgage-loan servicing violations by major financial institutions.

While at the DOJ, Mr. Casey led the Department's development of a first-ever policy for selection of compliance monitors in civil corporate settlements. Working with the Antitrust Division, he led the Department's response to the White House Executive Order on Competition in 2016. Mr. Casey was also part of the working group that developed the Department's September 2015 policy statement on "Individual Accountability for Corporate Wrongdoing" (the "Yates Memorandum").

In addition to the DOJ, Mr. Casey spent nearly six years litigating antitrust merger challenges at the FTC in Washington, primarily in the healthcare, telecommunications, energy, chemical and food industries.

As Assistant United States Attorney for the Middle District of Pennsylvania from 1999 to 2006, Mr. Casey prosecuted felony white-collar, narcotics, firearms and immigration crimes.

Mr. Casey earned his J.D. from The George Washington University Law School and his B.A. in mathematics from the College of the Holy Cross.
