David Berger represents plaintiffs in class actions with a special emphasis on data breach, privacy, and health care litigation.  He has represented data breach victims in some of the largest and most influential privacy cases, including litigation against Equifax, Anthem, Vizio, Adobe, Banner Health, and Excellus BlueCross BlueShield.  David has repeatedly obtained record-breaking settlements on behalf of his clients, including in the Equifax and Anthem data breach cases, which set successive records for the largest data breach settlement in history.

David is widely regarded as a leader in emerging litigation involving data breach and privacy, which is underscored by his broad technical expertise—from hacking techniques and cybersecurity controls, to industry standard IT practices, information security frameworks, and auditing processes.  He has deposed Chief Information Security Officers and information security professionals at Fortune 500 corporations, worked with expert witnesses on cutting-edge cybersecurity and damages theories, and supervised large-scale document review teams poring over millions of technical documents in a compressed timeframe. In addition, David holds the Certified Information Privacy Technologist (CIPT) certification through the International Association of Privacy Professionals, a program primarily designed for career IT professionals; this allows him to communicate directly with company witnesses, without the need for expert translation.

Outside of his litigation experience, David is an active member of the class action legal community, frequently speaking at conferences on data breach cases and security issues and other class action topics.  David serves as the Chair of the American Association for Justice’s Consumer Privacy and Data Breach Litigation Group and is an active member of the Sedona Conference’s Working Group on Data Security and Privacy Liability.

Prior to joining Gibbs Law Group, he served as a law clerk to the Honorable Laurel Beeler, Northern District of California (2011-2014). Before law school, David worked as a magazine editor and television presenter in Taiwan and managed an outdoor center on an island off the West Coast of Scotland.

    Key member of litigation team securing historic $1.5 billion class action settlement on behalf of 147 million consumers whose social security numbers and other private data were exposed in a 2017 data breach, described by the court as “the largest and most comprehensive recovery in a data breach case in U.S. history by several orders of magnitude." David played an integral role in negotiating key business practice changes, including overhauling Equifax's handling of consumers' personal information and data security and requiring that the company spend at least $1 billion for data security and related technology over five years.

    Key member of litigation team representing up to 3.7 million people whose personal health and other sensitive information were exposed in a large-scale 2016 data breach.
