Ms. Matzzie has been named one of the "500 Leading Lawyers in America" for the past five years by Lawdragon magazine based on her work representing whistleblowers. Some of her more prominent cases are:

  • A whistleblower case against Sodexo involving illegal retention of “off-invoice rebates” paid by food vendors from public schools and universities that were in effect kickbacks. The $20 million settlement was the largest non-Medicaid fraud settlement under the New York False Claims Act.
  • A qui tam whistleblower case against Chartwells, a school food services contractor, for allegedly serving poor quality or spoiled food to students and causing Washington, DC, public schools to pay millions more for the school meal program than it should have. The case settled for $19.4 million.
  • A whistleblower case brought by a doctor that resulted in stopping illegal importation of oncology drugs.
  • Two path-breaking cases alleging submission of false claims for Social Security Disability benefits by two private disability insurers, the Unum Group and Cigna.
