David Sherman is an associate in the Philadelphia office of Lewis Brisbois and a member of the Class Action & Mass Tort and Data Privacy & Cyber Security Practices. David represents commercial entities in complex multi-party disputes litigated in state and federal courts throughout the United States, with an emphasis on the defense of mass tort and putative class actions involving data privacy, products liability and consumer fraud claims.

David also represents corporate clients in commercial and business litigation involving breach of contract, breach of fiduciary duty, unfair competition, fraud and other business torts, as well as professional malpractice and errors & omissions matters, many of which involve complex electronic discovery issues.

Additionally, David counsels clients on best practices in information privacy and data security. Before an information security incident occurs, David facilitates incident response planning and risk assessments to enhance enterprise security posture and manage risk. When an information security incident occurs, David works as part of a Lewis Brisbois response team, often along with forensic consultants and law enforcement to evaluate the scope of potential data loss, identify affected individuals and ensure compliance with applicable federal, state and international laws.

Prior to joining Lewis Brisbois, David practiced with the New York office of a Philadelphia-based firm, where he defended design professionals and medical practitioners subject to professional liability claims, and represented business entities in commercial litigation. He also defended generic pharmaceutical manufacturers in multi district products liability matters.
