Review Kevin Darken

About Me

Kevin Darken divides his practice at Cohen, Jayson & Foster between complex civil litigation and white collar criminal defense, including both civil and criminal appeals. He has close to twenty years of experience in all aspects of litigation and trial. A renowned authority in health care fraud, false claims and qui tam (whistleblower) actions, Kevin plays an integral part in the firm’s most challenging cases, drafting the intricate legal arguments that go into briefs and motions. In civil litigation, Kevin has focused on bringing civil rights actions and business tort cases.


Kevin’s diverse background includes stints as a federal prosecutor, white collar criminal defense attorney and corporate litigator with a large national law firm. An assistant U.S. Attorney in the Middle District of Florida for six years, Kevin was the office’s Health Care Fraud Coordinator from 1994 to 1997, and served on the Justice Department’s National Health Care Fraud Working Group. During his tenure with the government, he received the Department of Health and Human Services Inspector General’s Integrity Award for outstanding leadership in the fight against health care fraud.


Kevin joined Cohen, Jayson & Foster from Trenam, Kemker, Scharf, Barkin, Frye, O’Neill & Mullis, where he was a partner concentrating on white collar criminal defense. While at Trenam, Kemker, Kevin successfully defended the CEO of a health care company accused of conspiring to defraud the Medicare program. This acquittal stands as the only instance in which a Tampa white collar defense attorney has ever cleared a defendant of health care fraud charges. Kevin also spent five years at the Washington, D.C.-based law firm, Crowell & Moring, representing defense contractors accused of fraud.


Kevin has published extensively in his area of authority, recently completing the sixth edition of his book, Defending and Preventing Health Care Fraud Cases: An Attorney’s Guide. He has also written articles for the Florida Bar Journal, the ABA’s Criminal Justice magazine, the Hillsborough County Bar Association’s Lawyer magazine, Corporate Counsel Quarterly, and is a frequent speaker on health care fraud.


Kevin is married, with twin sons and a daughter.
