Overview

Konstantine Diamaduros is a Shareholder of the Firm's Compliance and Investigations group. Konstantine concentrates on white-collar criminal defense, government investigations, and a broad range of high-stakes civil litigation involving shareholder disputes, contract disputes, tort claims with millions of dollars at stake, and commercial landlord-tenant disputes. Konstantine’s white-collar and investigative practice focuses primarily on whistleblower claims under False Claims Act, healthcare fraud, and criminal and grand jury investigations for individuals and companies. Konstantine also handles appellate matters in both state and federal court.

Konstantine helps guide individuals and businesses (large or small) through internal investigations when they or their employees are accused of committing violations of various criminal or civil laws—state or federal. Much of Konstantine’s day-to-day practice involves negotiating with private civil lawyers and government prosecutors. However, Konstantine also frequently interacts with civil and criminal investigators from the Federal Bureau of Investigation (FBI), Internal Revenue Service (IRS), and Securities and Exchange Commission (SEC).

Some of Konstantine’s recent, high-profile matters include:

  • Currently serving as co-counsel for a Fortune 500 company in several related False Claims Act qui tam cases pending in the United States District Court for the District of South Carolina. 
  • Currently serving as co-counsel for a Fortune 150 company in the South Carolina statewide opioid-related litigation.

  • Assisted in handling a complex internal investigation for a Fortune 500 company related to a nuclear project. 

Konstantine is licensed to practice in all South Carolina courts and the Fourth Circuit Court of Appeals. In addition, he has been admitted to practice pro hac vice (for the purpose of a particular case) in other courts, including the Southern District of Texas and the District of New Hampshire. 

Prior to joining the firm, Konstantine graduated from Wofford College and the University of South Carolina School of Law. After graduating from the University of South Carolina School of Law, Konstantine clerked for the Honorable Joseph F.
