Overview

Jeff Gleason is a partner in Crowell’s Health Care Group. An accomplished trial lawyer, Jeff helps his health care clients in high-stakes disputes with providers. Clients have turned to Jeff in a wide variety of matters including disputes over fraud, federal and state RICO statutes, state consumer protection laws, ERISA, breach of contract, the No Surprises Act (NSA) and the False Claims Act (FCA). In addition, Jeff has a proven track record of securing substantial affirmative recoveries on behalf of managed care organizations.

Prior to joining Crowell, Jeff was the co-founder and co-chair of the Health Care Practice at a national law firm, where he and his team secured many hundreds of millions of dollars in settlements and judgments on behalf of managed care organizations. Jeff and his team were also successful in defeating numerous high-value claims asserted against his clients.

Jeff also previously served as a Trial Attorney in the Civil Fraud Section of the Department of Justice. His work was pivotal in leading FCA investigations and litigation on behalf of the United States. His specialization in health care fraud cases resulted in settlements exceeding $100 million, including a landmark resolution against an individual physician. His exceptional service earned him a Special Commendation for Outstanding Service in the Civil Division, highlighting his commitment to justice and excellence in legal practice.

Pro bono service has been a cornerstone of Mr. Gleason’s practice. A highlight of his career was when he was honored with the President’s Award by the Boston Bar Association for his representation of six Guantanamo Bay detainees. He was also chosen as a Public Interest Fellow by the Boston Bar Association in recognition of his leadership in public interest law.
