Hamsa Mahendranathan is a partner at Whistleblower Partners. Hamsa has a varied False Claims Act practice that spans several industries, including healthcare, pharmaceuticals, cybersecurity, and military defense contracting. She also represents whistleblowers navigating the SEC Whistleblower Program, most notably in matters involving clinical trial fraud.

Hamsa started her legal career in the litigation group of Mayer Brown, where she litigated complex commercial cases and represented asylum applicants and human trafficking victims pro bono. After Mayer Brown, Hamsa worked at Constantine Cannon for nine years. At Constantine Cannon, Hamsa had a robust pro bono practice in addition to representing whistleblowers in FCA and SEC matters. Hamsa is currently a member of the Federal Bar Council’s Inn of Court, the New York State Bar Association’s Civil Prosecution Committee, and the President’s Council of the TAF Coalition, a non-profit organization that supports whistleblowers who expose fraud impacting government funds or financial markets. 

Hamsa received her J.D. from Columbia Law School, where she was a Wien National Scholar, a Harlan Fiske Stone Moot Court Semifinalist, and a Moot Court Editor. In her second year, she interned for United States Magistrate Judge Theodore H. Katz in the Southern District of New York. She also spent the summer after her first year of law school representing defendants sentenced to death in Louisiana. Hamsa received a B.A. in Economics and International Studies from the University of Illinois in Urbana-Champaign.

“Sometimes it can feel like you’re just trying to solve a problem, but everywhere you turn there’s a new roadblock. I love helping whistleblowers figure out the right path to move forward.”

Prior to law school, Hamsa worked on DCMA audits and employee stock options for a small government contractor.

Hamsa spends most of her free time with her spouse–a public school teacher–and their two feisty chihuahuas. She enjoys trying new foods, visiting animals at farm sanctuaries, and guessing the ending of BBC mystery shows. She is in constant competition with her many cousins for the title of Favorite Auntie to her many nieces and nephews.
