Michelle Kisloff is a proven litigator and advocate with more than 25 years of experience and a track record of success for her clients. 

Michelle helps her clients succeed when complex matters of data privacy and protection result in class action litigation and regulatory enforcement. She has been recognized by Chambers USA and Law360 as a national leader in Privacy and Cybersecurity, and leads our privacy litigation team nationwide.

Michelle also has deep experience litigating a broad range of commercial disputes, including health care contracts, insurance coverage issues, the enforcement of arbitration agreements, and post-merger fraud and indemnification claims.

Michelle defends and advises organizations accused of violating consumer privacy or misusing consumer data. She has successfully resolved investigations by the Federal Trade Commission and various state attorneys general (most often with non-public closures) and won early dismissals of proposed class actions related to data collection and alleged consumer tracking.

She also assists organizations in responding to some of the largest data breaches and state-sponsored cyberattacks on record – and in defending against the internal investigations, class action litigation, Congressional inquiries, and regulatory enforcement actions that follow these events.

Before joining Hogan Lovells, Michelle clerked for a federal district court judge in Pennsylvania and also worked for another law firm in New York City. Michelle volunteers as a member of the board of directors of My Sister's Place, which provides housing and support to women and children fleeing domestic violence in Washington, D.C.
