Ronald W. Chapman II, LL.M.


Chairperson of White Collar Defense & Government Investigations

About Me

Very few attorneys have achieved trial acquittals on behalf of health care clients charged with health care fraud and drug trafficking. Ronald W. Chapman II is one of them.

Ron’s trial background, health care experience, and strategic approach to litigation make him a highly sought-after health care defense and federal criminal defense attorney, by health care entities and practitioners nationally who are facing suspicion or charges of health care fraud, not maintaining DEA compliance, or unlawful prescribing.

A former prosecutor and recipient of an L.L.M. in health care, Ron’s specialization levels the playing field for clients facing government scrutiny in the health care and federal criminal defense arena. 

Notably, Ronald W. Chapman II achieved a trial acquittal of a prominent Johns Hopkins and Mayo Clinic physician charged with running several “pill mills” after a monthlong trial. Later, Ron secured a civil victory ensuring the return of over $6 million of assets seized by the government. Ron was also the lead trial lawyer in the acquittal of a prominent West Virginia physician charged with health care fraud and drug trafficking. Ron’s tenacity in and out of the courtroom, litigation experience, and health care experience have allowed a significant number of health care providers overcome government scrutiny.

Ron is also an in-demand author and speaker in the area of health care fraud, opioid prescribing, and government investigations. He has delivered lectures across the country including Harvard and Washington, D.C., as well as for various state medical societies, and criminal defense organizations. He has also published peer-reviewed articles on the topic of health care fraud and physician drug trafficking defense, and he has a deep understanding of medical expert witnesses.

As a former prosecutor and veteran of the U.S. Marine Corps, Ron is comfortable dealing with the Department of Justice and other federal agencies including the DEA, FBI, HHS and FDA.

Ron is a graduate of Loyola School of Law, where he received his Master of Laws (LL.M.) with a concentration in health care compliance. He has been named as a 2015-2020 Super Lawyers Rising Star for his contributions to criminal law and health care law, and he was recognized as a Michigan Lawyers Weekly Top Lawyer. Ron served as co-chair of the Michigan Bar Health Care Law Section’s Substantive Law Committee.

Ron’s representative clients include a multistate behavioral health corporation, a national pharmacy chain, a national hospice provider, a former board of pharmacy member, a regional interventional pain practice, and a significant number of physicians and health care practices, pharmacies and clinics in Metro Detroit and across the U.S. that have faced government investigations or criminal charges.

Ron was an officer in the U.S. Marine Corps, and he was previously deployed to combat in Afghanistan. He achieved the rank of Captain and earned the Navy and Marine Corps Commendation Medal and Navy Achievement Medal, among other awards.

Ron Chapman II is an amazing attorney. I had different representation when I asked Ron to take my case. My previous attorney's advice was to cooperate with my licensing board, accept any deal they offered me and hope that I was not sued in the process. This did not sound like the best plan because I did not do what I was accused of doing. Ron worked with his team to present my case to an Administrative Law Judge in a manner that I supported and ultimately resulted in a recommendation that my licensing board dismiss the compliant filed against me. When my board opted to sanction me in spite of this recommendation, Ron filed an appeal with the MI Appellate Court. Finally after three long years, I was exonerated when that Court ordered my licensing board to dismiss the complaint. Thank you Ron and Chapman Law!!!
