Biography
About Mark D. Seltzer
Mark Seltzer represents corporations, executives and professionals in government investigations and enforcement actions and related complex litigation.
What do you focus on?
In recent years, I have focused my practice on representing pharmaceutical companies and their executives, medical device manufacturers and their executives, clinical diagnostics manufacturers and other health care providers in government health care fraud investigations and related civil litigation under the federal False Claims Act and state counterparts; the federal Food, Drug and Cosmetic Act; the Medicare/Medicaid Anti-Kickback Statute; the Medicaid Drug Rebate Statute; and state consumer fraud statutes.
Outside the health care industry, I represent senior corporate executives in securities enforcement investigations, and financial institutions in various enforcement matters.
I have extensive experience in conducting confidential internal investigations for corporate clients. I regularly advise corporations on the design, implementation and monitoring of compliance programs.
Formerly, I was a federal prosecutor for 13 years both in Miami, as an Assistant United States Attorney for the Southern District of Florida and, in Boston, as Director of the New England Bank Fraud Task Force of the United States Department of Justice.
