As one of the country’s top litigators, Karen focuses her practice on complex civil litigation as well as crisis management—helping her clients solve their biggest problems both in and out of the courtroom. Karen was named a 2017 Litigator of the Year by The American Lawyer magazine, for her work in “high-stakes, high-profile and hard-fought” cases.
In the past several years alone, Karen has secured important trial wins for some of the country’s most prominent companies, including Apple, Uber and Oracle. Karen led the all-female BSF team that prevailed in a seven-day trial on behalf of Uber in a case in federal court involving Boston’s largest taxi conglomerate seeking $750 million in damages. She led BSF’s defense of Uber in a billion-dollar trade secrets case brought by Waymo regarding the future of self-driving cars. And she secured a $3 billion summary judgment win on behalf of Apple against Qualcomm. As part of her commitment to public service, she fought and won a two-year legal battle in local and federal courts to secure budget autonomy for the District of Columbia. And she is co-lead counsel in a lawsuit against the neo-Nazis and white supremacists responsible for the deadly violence in Charlottesville, VA. Karen is also a prior recipient of the ADL SHEILD award for her role in a prosecution of three men who conspired to use a website as a platform to solicit murder and promote violent extremism.
Prior to joining the firm, Karen served in all three branches of government. As an Assistant U.S. Attorney in the Eastern District of Virginia, she tried to jury verdict numerous multi-defendant cases and led complex investigations. She served as Associate White House Counsel, representing the Executive Office of the President in congressional investigations and overseeing litigation. Karen served as a law clerk to Judge Merrick B. Garland of the D.C. Circuit Court of Appeals and to Justice Stephen G. Breyer of the U.S. Supreme Court. Earlier in her career, Karen served as communications director and senior advisor to then-Senator Hillary Clinton. Her work preparing candidates for political debates, including President Barack Obama and Hillary Clinton, has received extensive media coverage.
Karen has been named one of the National Law Journal’s Outstanding Women Lawyers, a Litigator of the Week three times by The American Lawyer and once by Global Competition Review, one of Elle Magazine’s Most Compelling Women in Washington D.C., and has been recognized as one of the country’s top ten female litigators by Benchmark Litigation.
