Geoffrey (Jeff) R. Kaiser, who has extensive experience in enforcement matters affecting the healthcare industry, concentrates his legal practice on healthcare fraud and regulatory compliance issues, white collar criminal defense, False Claims Act litigation, integrity monitoring, and internal investigations. As head of the Compliance, Investigations and White Collar Practice Group, and senior counsel in the Health Services Practice Group, Jeff is frequently called upon to handle matters implicating a range of healthcare fraud and abuse laws, including the False Claims Act and the Anti-Kickback Statute. The Health Services Practice Group at Rivkin Radler has been listed in the prestigious Legal 500. The practice is also recognized as “notable” by Chambers USA.

As Chief of Health Care Fraud Prosecutions and Deputy Chief of Public Integrity in the Eastern District U.S. Attorney’s Office, Jeff directed investigations against individuals and corporations facing health care fraud allegations under a variety of criminal and civil statutes.  In many instances, those investigations were rooted in allegations brought by whistleblowers under the False Claims Act. Jeff also exercised oversight responsibilities within the Public Integrity Section for all healthcare fraud cases within the Eastern District of New York. He received many recognitions and honors for his efforts as a federal prosecutor.

Jeff received his B.A. with Honors from the University of Virginia, where he also graduated Phi Beta Kappa.  He earned a J.D. from New York University School of Law, where he served on the Moot Court Board.  After graduating from law school, Jeff served for two years as law clerk to the Hon. Fritz W. Alexander II, an associate judge on New York State’s highest court, the New York Court of Appeals.

A frequent writer and speaker on a range of legal topics, particularly in the areas of healthcare fraud and compliance, Jeff was named a Super Lawyer in the Metro New York area, 2012-2021. Jeff is an adjunct professor of law at St. John’s University School of Law, where he teaches Health Care Fraud.
