David A. Ring


David is nationally known for representing companies and individuals when the stakes are greatest, whether investigating sensitive internal matters, defending against criminal charges, litigating complex civil matters or building compliance programs for companies confronting  enforcement actions. David is a seasoned litigator with decades of trial experience and, as a result of his successes as a government-appointed monitor and in-house counsel, is nationally known for rebuilding corporate compliance programs under urgent circumstances. He is Partner-in-Charge of the firm's Washington, DC office; a member of the White Collar Defense, Investigations and Corporate Compliance Practice Group; and Co-chair of the International Trade Compliance Practice Group.

Over the past several years, David has represented clients in a wide-variety of high-stakes matters. A sample includes:

  • Defending a privately owned global electronics manufacturer that was raided by federal agents for alleged violations of U.S. sanctions, ultimately obtaining a declination from the U.S. Department of Justice (DOJ), a no-penalty decision from the U.S. Department of Commerce, and quashing law enforcement's leak of sealed materials to the press.
  • Defending a company in an criminal environmental matter brought by the DOJ and the Environmental Protection Agency, ultimately resolving the matter with no criminal charges against individuals or the operating company and with a criminal fine against a holding company that was no longer in operation.
  • Representing a Fortune 100 insurance company by bringing suit against a chain of Texas medical providers who were alleged to be involved in fraudulent billing practices against the insurance company.
  • Representing a Fortune 1000 company whose CEO and others were threatened with a civil Racketeer Influenced and Corrupt Organizations Act (RICO) violation, which after David's involvement was never filed.
  • Conducting an internal investigation involving alleged accounting fraud, for a Fortune 100 company.
  • Serving as a U.S. State Department appointed monitor for a Washington state company that entered a consent agreement with the government due to deficiencies in its international trade compliance program.

David has been recognized as a "Litigation Star" since 2015 in Benchmark Litigation's White Collar Crime/Enforcement/Investigations category.

David's unique experiences as a defense attorney, government-appointed monitor, and compliance-guru have made him a popular speaker at compliance conferences in the US and abroad. He has been invited to speak at conferences and private events in cities such as London; New York; Washington, DC; Los Angeles; and Seattle, including invitations extended by the U.S. State Department (directly and through the Society for International Affairs) and Homeland Security. 

Prior to Wiggin and Dana, David held senior positions at United Technologies Corporation (UTC), including Global Director of Compliance Investigations, Associate General Counsel for International Trade Compliance for United Technologies Aerospace Systems (formerly Hamilton Sundstrand), and Director of Business Practices for the Americas. In these positions, David was responsible for overseeing and conducting critical internal investigations worldwide, enhancing the company's compliance programs, and liaising with law enforcement.

Before joining UTC, David served 17 years in the DOJ: three years in the DOJ's Public Integrity Section and 14 years in the U.S. Attorney's Office for the District of Connecticut, where his roles included Chief of the Hartford office, co-lead of the Anti-Terrorism Task Force, and lead of Hartford's Organized Crime and Drug Enforcement Task Force. David prosecuted a wide variety of crimes, including public corruption, bank fraud, healthcare fraud, securities fraud, tax fraud, money laundering, terrorism, sanctions violations, violent crime, and capital murder. He tried numerous cases to juries and was a frequent trial practice instructor at the DOJ's National Advocacy Center. David is a recipient of the DOJ's Director's Award and the U.S. Attorney's Standing Tall Award.

David serves on the board of directors for Lawyers Collaborative for Diversity; the board of overseers for the District of Connecticut Criminal Justice Act Panel; and the Connecticut Bar Association's Diversity and Inclusion Committee. His most rewarding extracurricular activity involves teaching law in the Hartford Public Schools, introducing diverse students to important legal principles, real-life institutions and officials, and the challenge of mock trials. He also has served on selection panels for the U.S. District Court for the District of Connecticut and has conducted confidential investigations for the court.

David clerked for the Hon. Karen LeCraft Henderson on the U.S. Court of Appeals for the DC Circuit.
