Lowey Dannenberg Cohen & Hart

What Lowey Dannenberg Cohen & Hart does

Lowey Dannenberg Cohen & Hart, P.C. is a U.S. plaintiff-side complex litigation law firm founded in 1967 in White Plains, New York, with a second office in West Conshohocken, Pennsylvania, and a headcount of 11–50 employees. The firm represents institutional and individual investors, public pension plans, third-party payors, and consumer classes across five practice areas: Data Privacy, Commodities/Whistleblower, Antitrust, Healthcare, and Securities. Counsel has served as court-appointed co-lead counsel in matters such as Shell Eggs Antitrust, Ramaco Resources securities class actions, and the Google Assistant privacy litigation, and has secured multiple eight- and nine-figure recoveries, including a $386.5 million bond market antitrust settlement, a $95 million Apple consumer privacy settlement, a $68 million Google privacy settlement, and a $63.2 million Amitiza end-payor generic-drug verdict.

The firm operates on a contingency fee model across securities, antitrust, consumer protection, data breach, and mass arbitration matters, recovering a percentage of client settlements or judgments. Case origination combines court-appointed co-lead counsel appointments, portfolio monitoring contracts with public pension plans, and press-release-driven outreach (GlobeNewsWire/FinancialContent) soliciting investor participation in active matters. The firm has also developed Claim Magic, an in-house consumer-facing case management portal where class members check eligibility, retain counsel, upload documents, track case status, and receive settlement payments.

Recent strategic activity includes the 2025 lateral hires of former U.S. Congressman Matthew A. Cartwright to lead the Healthcare Litigation Team and former Assistant Attorney General Joseph Nielsen to deepen the antitrust bench, alongside 2026 Chambers & Partners recognition in Antitrust: Mainly Plaintiff New York. Distribution is primarily direct client engagement (White Plains and West Conshohocken offices) supported by the firm's website, newsletter, and organic social presence on LinkedIn, Facebook, and Instagram. The firm is privately held as a New York professional corporation with no parent company or institutional investment structure.
