Dan Eisenberg is an experienced litigator and investigator who practices primarily in New York and Washington, D.C. He represents individuals and institutions in complex constitutional, civil rights, and commercial disputes.
Dan’s trial record includes securing the largest settlement in history for the death of an incarcerated person in New York State custody on the eve of closing arguments following a two-week jury trial in the Southern District of New York; securing one of the largest settlements in New York history in a school suicide case after the first day of trial in the Southern District of New York; and winning judgment against U.S. Customs and Border Protection over tariffs on a breakthrough HIV medication after a bench trial in the U.S. Court of International Trade, which was affirmed by the U.S. Circuit Court of Appeals for the Federal Circuit. He has successfully resolved disputes in confidential arbitrations and other trial-like proceedings.
Immediately prior to joining the firm, Dan served as Deputy Staff Director & Senior Counsel to the U.S. Senate Permanent Subcommittee on Investigations, the primary investigative body of the U.S. Senate, where he led bipartisan investigations into government misconduct. Dan’s investigations culminated in Congressional hearings and reporting on the abuse of pretrial detainees at a prominent federal prison; unchecked sexual assault of prisoners by Federal Bureau of Prisons employees at multiple facilities across the country; and the Department of Justice’s failure to oversee deaths in state and local custody. This public record established the factual predicate for reforms within the Department of Justice and by Congress, including passage of the Federal Prison Oversight Act and the Prison Camera Reform Act.
Dan’s current engagements include representing public servants (such as a former Mayor of the City of New York and the Attorney General of the State of New York) in civil rights disputes, the former Chief Executive Officer of a maritime shipping company in a dispute with a publicly traded company about compensation, whistleblowers testifying before the United States Senate, a woman who was subjected to workplace sexual harassment and discrimination, and the families of people who died while incarcerated.
Dan began his legal career as a Law Clerk to the Honorable Robert P. Patterson, Jr., U.S. District Judge for the Southern District of New York, followed by six years at Patterson Belknap Webb & Tyler LLP, where he represented large corporations and executives in complex commercial litigation, monitored a large municipal police force pursuant to a Department of Justice Consent Decree, defended New York cultural institutions in cases involving disputed provenance of renowned fine art, and won a favorable settlement for residents of Chinatown who lost their property in a five-alarm fire.
Dan’s work has been featured in The New York Times, Associated Press, Reuters, Time Magazine, The Washington Post, The Marshall Project, CNN, MSNBC, NPR, and other national and local media outlets. He serves as an Advisory Board Member of the Alliance of Families for Justice, a non-profit organization that supports and advocates for incarcerated people and their families. He has guest lectured on Congressional investigations at Cardozo School of Law and Brooklyn Law School and taught criminal procedure as an Adjunct Professor at St. Francis College.
