former federal prosecutor, Jonathan counsels companies and individuals through their toughest and most complex legal situations.
Jonathan focuses on white collar criminal defense, federal investigations brought under the False Claims Act, and litigation against the government and whistleblowers, with an emphasis on matters within the healthcare industry. Clients nationwide seek Jonathan's experience in guiding them through federal investigations. As a former federal prosecutor with extensive experience in both criminal and civil matters, he has the wisdom needed to navigate clients across the harshest of legal terrains. His courage in confronting government challenges as a top-tier trial lawyer, combined with his stature as a leader in the healthcare enforcement community and role as an adjunct law school professor teaching white collar crime, make him a distinguished figure in the field.
At the Department of Justice, Jonathan earned a reputation as a top white collar prosecutor and trial lawyer. Jonathan was a key member of multiple international healthcare fraud takedowns and prosecuted a series of high-profile financial crime cases. Jonathan prosecuted doctors, lawyers, pharmacists, executives, and even a pastor for white collar crimes during his time as a federal prosecutor, and was touted for his trial skills, with one federal judge calling Jonathan’s trial performance “masterful,” following a complex healthcare fraud trial. Jonathan also handled major civil investigations and litigation against companies and individuals under the False Claims Act, resulting in record-breaking settlements and judgments. For his work, Jonathan won some of the highest honors bestowed upon federal prosecutors by the DOJ, FBI, HHS-OIG, and DEA.
Jonathan now uses that experience to guide clients through federal investigations of all kinds, to litigate cases against and involving the government, and to run effective and right-sized internal investigations for corporations. Many of Jonathan’s clients are in the healthcare industry, including health systems, physician groups, and other healthcare companies, along with medical professionals and executives, and Jonathan serves as a vice chair of the American Health Law Association’s Fraud and Abuse Practice Group. But clients in all industries count on Jonathan to solve their toughest problems in creative, efficient, and reliable ways.
Jonathan is a leader in the white collar community, was lauded by Legal500 for "his deep knowledge of FCA federal investigations," and is recognized as a 2025 Litigation Star by Benchmark Litigation. He teaches white collar crime as an adjunct professor of law at Mercer University School of Law in Macon, Georgia.
