David I. Ackerman


David Ackerman is a civil litigator with experience representing clients in complex national and international disputes at both trial and appellate levels. He plays a leading role in litigation filed on behalf of governments, state attorneys general, and other entities in order to advance public health and consumer interests.

David’s practice includes pursuing litigation targeting the alleged deceptive marketing and over-distribution of opioids that led to the addiction crisis, which claims thousands of American lives each year. 

David’s experience brings added understanding of considerations by defendants and companies involved in litigation. Prior to joining Motley Rice, he was a partner based in the Washington, D.C. office of a global law firm where he represented clients in state and federal courts, private arbitrations, and Federal Trade Commission and administrative proceedings. Among other representations at his former firm, David obtained dismissal of tort and contract claims brought against an African nation under the Foreign Sovereign Immunities Act, served as litigation counsel for a nationwide dental management organization, and represented a major insurance company and its former CEO and CFO in a securities fraud class action in the Southern District of New York. David also represented a Medicare provider in more than 6,000 recoupment appeals before the Office of Medicare Hearings and Appeals, and counseled clients who were the subject of Federal Trade Commission investigations regarding their marketing practices. 

While in law school, David served as a law clerk in the Federal Trade Commission’s Division of Marketing Practices. He began his career at a D.C. law firm as a litigation associate, where he represented clients in marketing practices investigations conducted by the FTC and dozens of state attorneys general, and represented employees of a former Fortune 500 company in DOJ and SEC investigations.
