Jeanne Markey


Jeanne A. Markey, is a Partner at Cohen Milstein and Co-Chair of the firm's Whistleblower/False Claims Act practice group.  She has successfully represented whistleblowers in federal and state cases across the country.  Ms. Markey has extensive experience in Qui Tam litigation in the health care, defense and education industries, and has represented whistleblower clients in the public housing sector. 

Ms. Markey is co-lead counsel in United States of America et al., ex rel. Lauren Kieff, v. Wyeth, a high-profile whistleblower case against pharmaceutical giant Wyeth (recently acquired by Pfizer). The lawsuit alleges that Medicaid, the healthcare program for the poor which is jointly funded by the federal and state governments, was defrauded when Wyeth falsely inflated the price of the acid suppression drug Protonix Oral from 2001 through 2006.  Thirty-six states and the District of Columbia have joined with the United States to intervene in the Wyeth case – more states than have ever intervened in any other U.S. Qui Tam case.

She also served as the primary attorney representing the putative class in Benzman v. Whitman, a class action in Manhattan and Brooklyn against the U.S. Environmental Protection Agency. The claims were based on class members’ exposure to contaminants  contained in World Trade Center interior dust resulting from the 9/11 attacks.  

Ms. Markey is admitted to practice law in the Commonwealth of Pennsylvania, the Eastern District of Pennsylvania and to the First Circuit Court of Appeals, Second Circuit Court of Appeals, and Eleventh Circuit Court of Appeals.  She is a member of Taxpayers Against Fraud, a nonprofit, public interest organization dedicated to combating fraud against the Federal Government through the promotion and use of the Federal False Claims Act and its Qui Tam provisions, the Association of Qui Tam Attorneys, and frequently speaks about developments in the Qui Tam field. She received her B.A. (cum laude) from Colgate University and her J.D. from Cornell University Law School.
