Super Lawyers names Phillips & Cohen whistleblower attorneys to its top 2021 lists

WASHINGTON, DC, Oct. 20, 2021 — Six Phillips & Cohen attorneys have been recognized by Super Lawyers for their work representing whistleblowers.

Phillips & Cohen partners Mary Louise Cohen, Erika Kelton, Peter Chatfield, Colette Matzzie and Claire Sylvia have been named to Super Lawyers’ 2021 list of top attorneys in their respective regions. Phillips & Cohen associate Molly Knobler was recognized by Super Lawyers in its “Rising Stars” category.

Phillips & Cohen attorneys are repeat honorees, selected to Super Lawyers’ lists every year since 2019.

  • Mary Louise Cohen, a founding partner of the firm, was instrumental in building the modern qui tam practice. Her work representing whistleblowers has earned her the title “the queen of qui tam” as well as the Lifetime Achievement Award from Taxpayers against Fraud Education Fund.
  • Erika Kelton, an internationally recognized whistleblower attorney, has won record-setting cases brought under the False Claims Act and under the whistleblower programs of the SEC and CFTC. Her cases have yielded a $3 billion healthcare fraud settlement by GlaxoSmithKline and earned an international whistleblower client a $32 million award from the Securities and Exchange Commission.
  • Claire Sylvia is the author of a leading treatise on the False Claims Act and has represented whistleblowers in many qui tam cases involving healthcare fraud and defense contractor fraud. She recently represented the whistleblower in what is likely the first-ever False Claims Act case involving cybersecurity issues in a qui tam case against Cisco Systems that settled for $8.6 million.
  • Colette Matzzie’s groundbreaking case against electronic health records vendor eClinicalWorks is an important industry first. It yielded a $155 million settlement and was prominently featured in the CBS series “Whistleblower.” Ms. Matzzie regularly represents whistleblowers in healthcare fraud, defense contractor fraud and other government procurement fraud cases.
  • Peter Chatfield has represented whistleblowers in significant qui tam lawsuits taking on major healthcare companies. His whistleblower cases have been important pieces of an $881 million settlement by HCA, a $425 million settlement by Cephalon and a $118.7 million by Adventist Health Systems.
  • Molly Knobler, named to Super Lawyers’ 2021 “Rising Stars” list, represents whistleblowers in a wide variety of qui tam matters, including the recent Prime Healthcare case ($37.5 million settlement) and a case against defense contractor AAR ($11 million settlement). She has been recognized as a “Rising Star” annually for the past three years.
