Biography
Cari Campen Laufenberg, class action attorney serving Seattle
Cari Campen Laufenberg is a partner based in Seattle, WA. The practice focuses on Class Action, Employment, and General. Cari has over 23 years of legal experience. Currently practicing at Keller Rohrback L.L.P.. Rated 4.8 out of 5 from 12 client reviews. Cari works from Seattle, Washington and takes on class action matters across the region.
Since joining Keller Rohrback in 2003, she has played a key role in obtaining multi-million-dollar recoveries for consumers, employees, and shareholders in many of the firm’s largest and most complex cases, including cases involving Meta Platforms, Inc., T-Mobile, Anthem Inc., Sony Pictures Entertainment Inc., Marsh McLennan Companies, Goodyear Tire & Rubber Co., HealthSouth Corporation and The Williams Cos.
While having excelled in the realms of corporate fraud, fiduciary duty, and ERISA, Cari has also developed an excellent reputation litigating data privacy cases by securing meaningful relief for her clients and class members. She has been instrumental in the foundation and growth of the firm’s data privacy practice group. In that effort, she has served as Co-Lead Counsel in a number of high-profile data breach cases for which she and the KR team have achieved outstanding results: In re T-Mobile Customer Data Security Breach Litigation, MDL No. 3019 (W.D. Mo.) (obtaining the second largest data breach settlement to date); In re 21st Century Oncology Customer Data Security Breach Litigation, MDL No. 2737 (M.D. Fla.) (securing a meaningful settlement despite the company declaring bankruptcy), and as Class Counsel in Fox v. Iowa Health System (W.D. Wis.) (securing a favorable settlement for approximately 1.4 million victims of the UnityPoint Health data breach).
She also currently serves as Co-Lead Counsel in several other multidistrict data breach cases including In re 23andMe, Inc. Customer Data Security Breach Litigation, MDL No. 3098 in the Northern District of California-a case concerning the exposure of highly sensitive personal and genetic information for 6.9 million customers and In re T-Mobile 2022 Customer Data Security Breach Litigation, MDL 3037, in the Western District of Missouri-a case involving a November 2022 data breach impacting 37 million customers of U.S. wireless carrier T-Mobile.
Cari has served in leadership positions in other prominent consumer class-action cases as well, including as Interim Lead Class Counsel in In re EpiPen ERISA Litigation (D. Minn.) and her appointment to the Plaintiffs’ Steering Committee in In re Oral Phenylephrine Marketing and Sales Practice Litigation, MDL No. 3089 (E.D.N.Y.).
She also played a fundamental role in the In re Facebook, Inc. Consumer Privacy User Profile Litigation, MDL No. 2843 (N.D. Cal.), in which, together with co-lead counsel, KR achieved a $725 million settlement-the largest recovery ever achieved in a private data privacy class action and the most Meta has ever paid to resolve a private class action.
Over the past almost 20 years, Cari’s background in nonprofit management and public administration has served her clients well. She is adept at organizing large complex cases, working collaboratively with other counsel, and developing a cogent strategy which achieves short-term goals and long-term successes. Before joining Keller Rohrback in 2003, Cari served as a judicial extern for the Honorable Barbara Jacobs Rothstein of the U.S. District Court for the Western District of Washington. She is a frequent speaker at national conferences on class actions, identity theft and privacy, and other complex litigation topics.
