Ron Chapman II
A Champion of Justice in Federal Defense
Ronald W. Chapman II stands out as one of the nation’s most formidable federal criminal defense attorneys, renowned for his exceptional success in high-stakes litigation. Based in Detroit but practicing nationwide, Ron has built a reputation on winning the unwinnable. A former prosecutor and U.S. Marine Corps Judge Advocate, he combines insider understanding of the government with the tenacity of a battlefield-tested leader. His trial record is virtually unparalleled—in an era when only about 0.6% of federal defendants are acquitted, Ron has secured multiple full acquittals in just the past few years. Those who have seen him in action agree that he is anything but ordinary: a veteran federal judge praised Ron as “one of the most talented attorneys” they had seen in 20 years on the bench. For clients facing the fight of their lives, Ron Chapman II is the ally you want in your corner.
Very few lawyers win against the Feds. This is who you want on your side in a federal courtroom! He wins at a high percentage because he is extremely prepared for trial and knows exactly what he is doing and how to offset or rebut anything prosecutors may try.

From the Battlefield to the Courtroom
Early Career and Military Service
Ron’s journey to becoming a top defense lawyer began with service and sacrifice. As a Marine Corps officer in the Global War on Terror, Captain Chapman honed elite investigative skills by leading complex probes into weapons trafficking, narcotics rings, and counterterrorism threats. Serving as a Judge Advocate (JAG), he prosecuted and defended cases within the military justice system, gaining a deep understanding of how government cases are built. This experience instilled in him a military precision and discipline that he now brings to every client’s case. These early roles—Marine officer and prosecutor—forged Ron’s comprehensive view of the justice system from both sides. He witnessed firsthand the tactics authorities use and the missteps they can make. This battlefield-to-courtroom background gave Ron an investigative savvy and strategic mindset that few attorneys can match. It’s the foundation of his ability to level the playing field for those caught in the crosshairs of a federal investigation.
After his military service, Ron returned home to Michigan with a mission: to defend individuals and professionals against the same powerful government agencies he once represented. He devoted himself to mastering health care and white-collar law, recognizing that doctors, executives, and ordinary citizens often face overwhelming odds when accused by federal authorities. To further specialize his expertise, Ron earned a Master of Laws (LL.M.) in Health Care Law from Loyola University Chicago, an advanced degree that equipped him with cutting-edge knowledge at the intersection of health care and law. Armed with this unique combination of real-world investigative experience and academic insight, Ron W. Chapman II launched into private practice, determined to protect clients with the fierceness of a Marine and the acumen of a scholar.

Record-Setting Trial Victories in High-Stakes Cases
Once in private practice, Ron quickly became a formidable advocate for clients facing federal prosecution, especially in health care fraud and controlled-substances cases. Over the past decade, he has racked up an unmatched list of trial acquittals, case dismissals, and government declinations—outcomes so extraordinary that they have garnered national attention. His results speak for themselves and often reshape the law. In June 2022, for example, Ron handed the U.S. Department of Justice a stunning defeat in what local media called “one of the biggest losses for the U.S. Attorney’s Office in the last 10 years.” In United States v. Bothra, Ron and his team defended a Detroit-area pain management physician and colleagues accused in a $550 million health care fraud and opioid distribution case—one of the largest such federal indictments in Michigan’s history. After years of litigation and a grueling multi-week trial, the jury returned not guilty verdicts across the board. Five physicians were fully acquitted on all counts, despite prosecutors alleging unlawful prescribing. This victory not only saved the defendants from life-altering prison time but also sent a powerful message that a well-prepared defense can beat even the biggest of federal cases.

Frequent High Profile Victories
Ron’s string of courtroom triumphs did not stop there. In case after case, he has proven his ability to dismantle the government’s accusations and persuade juries to side with the defense. Some of his landmark victories include:
United States v. Bothra (E.D. Mich. 2022): Acquittal of five physicians in a $550 million health care fraud and drug trafficking prosecution—a case so significant that the press dubbed it the largest federal acquittal in Detroit in a decade. The doctors were accused of unlawfully prescribing 13 million opioid doses, but after Ron’s defense, all were cleared of every charge.
United States v. Pompy (E.D. Mich. 2022): Acquittal of Dr. Lesly Pompy, a pain specialist alleged to have run a $6 million fraudulent opioid scheme. Ron proved to the jury that the physician’s actions were within the bounds of legitimate medicine, overcoming complex medical evidence and intense public scrutiny.
United States v. Sachy (M.D. Ga. 2023): Mid-trial judicial dismissal of all charges against Dr. Thomas Sachy, who was accused of unlawful prescribing that allegedly caused patient deaths. Partway through this federal opioid trial, Ron’s cross-examinations exposed such gaping holes in the prosecution’s case that the judge took the rare step of granting a Rule 29 motion for acquittal before the defense even had to put on its case. This extraordinary outcome—essentially ending the trial early in the defense’s favor—underscored Ron’s ability to dismantle the government’s evidence at its weakest points.
United States v. Kousa (E.D. Ky. 2023): Full acquittal of a Kentucky physician charged by the DOJ’s Appalachian Regional Prescription Opioid (ARPO) Strike Force with drug trafficking and health care fraud. Going up against a specialized federal strike force, Ron achieved a complete defense victory, freeing the doctor of all charges and defeating an initiative aimed at making an example of prescribers in Appalachia.
United States v. Hansen (E.D. Ky. 2024): Ten-count acquittal of Dr. Kendall Hansen, who faced a sweeping indictment for opioid distribution and fraud. Ron’s success in this trial marked yet another blow to federal opioid task force prosecutions. Despite the DOJ throwing significant resources at the case, the jury found every count in favor of the defense, reflecting Ron’s ability to humanize his client and cast doubt on prosecutorial overreach.

Nationwide Success
These outcomes are not isolated. Ron has delivered favorable results across the country, often in jurisdictions and cases where defendants rarely prevail. He has obtained acquittals and dismissals from Michigan to Puerto Rico to West Virginia, defending physicians, pharmacists, and business owners in cases involving allegations of Medicare fraud, improper opioid prescribing, money laundering, and more. For instance, he won the acquittal of a Johns Hopkins–trained Michigan physician on over 30 drug trafficking counts in state court, and he secured the pretrial dismissal of a $5 million Medicare fraud case against an emergency room doctor in Puerto Rico. In another West Virginia case, United States v. Aggarwal, Ron earned a full acquittal for a clinic doctor accused of unlawful Suboxone prescribing. Time and again, even when facing “slam-dunk” government evidence or widespread public condemnation, Ron has proven that rigorous defense can defy the odds.
It’s little wonder that his peers and adversaries acknowledge his unmatched trial results. Federal judges have openly recognized Ron’s courtroom skills as among the very best to come before them. Thanks to this track record, prosecutors who find themselves up against Ron Chapman II know they face significant litigation risk—a fact that often leads to better plea offers or case dismissals for his clients. Simply put, Ron’s work defies the odds, giving his clients a fighting chance even in the face of daunting federal charges.
“Ron has proven to be the most knowledgeable and strategic attorney that I've come across.”

A Force for Change at the Highest Courts
Beyond his remarkable trial victories, Ron is also an influential appellate advocate who has shaped law at the national level. He has litigated cases before the United States Supreme Court and in federal Courts of Appeals spanning multiple circuits. In fact, Ron has represented clients (and their causes) in front of the highest court in the land—and won. Most notably, he was part of the team that fought for physicians’ rights in the landmark opioid prescribing case Ruan v. United States (2022). In Ruan, the Supreme Court unanimously sided with doctors, holding that the government must prove a doctor knowingly or intentionally acted unlawfully when prescribing controlled substances. This pivotal decision raised the legal standard needed to convict physicians, rejecting the vague “objective good faith” standard that some lower courts had applied. Ron’s advocacy in the case—including representing a policy group as amicus curiae to urge stronger protections for well-meaning doctors—helped secure a victory that reshaped the landscape of pain management prosecutions. Thanks to Ruan, doctors nationwide now have a powerful precedent to assert their good-faith clinical judgment without being automatically deemed criminals.
I've dealt with several attorneys in my career however, absolutely none compared to Mr. Chapman II.

Supreme Court Advocacy
Ron followed up that success with another Supreme Court win in Naum v. United States (2022). In Naum, he represented a West Virginia physician accused of improperly prescribing Suboxone. After Ron took the case up, the U.S. Supreme Court vacated the doctor’s conviction, sending it back to be reconsidered under the new standards set by Ruan. This outcome not only saved the physician’s career and freedom but also cemented Ron’s role in shaping the interpretation of federal prescribing laws. In total, Ron has represented at least two defendants before the Supreme Court and succeeded in wiping out their convictions—a feat many attorneys only dream of. He is admitted to practice before the U.S. Supreme Court and brings to appellate advocacy the same relentless drive that he shows in trial.
On the federal appellate circuit level, Ron’s expertise is equally far-reaching. He has briefed and argued cases in the Fifth, Sixth, Ninth, and Eleventh Circuits of the U.S. Courts of Appeals, often on cutting-edge issues of health care fraud, constitutional rights, and administrative law. His ability to navigate complex legal questions across multiple jurisdictions has made him a go-to lawyer for appeals that have industry-wide implications. Whether it’s challenging a novel legal theory or defending a hard-fought trial victory on appeal, Ron is adept at crafting persuasive arguments that resonate with appellate judges. His appellate work, combined with his Supreme Court experience, means that clients not only have a trial lawyer who can win in the courtroom, but also a legal strategist who can protect those wins (or overturn losses) on appeal if necessary.
Importantly, Ron’s national practice isn’t limited to cases he personally tried. Other lawyers frequently bring him in to consult or co-counsel on high-stakes federal cases around the country, recognizing his special proficiency in federal health care and criminal matters. He is admitted to numerous U.S. District Courts and often obtains court permission to appear pro hac vice in jurisdictions coast to coast. From the Midwest to the Deep South, from the East Coast to the Caribbean, Ron has defended clients in federal courtrooms of many states. No matter where a case takes him, he approaches each venue with thorough knowledge of local rules and a respect for the community, while applying a consistent overarching strategy: outthink and outwork the government at every turn. This combination of trial prowess and appellate insight makes Ron Chapman II a true full-spectrum defense attorney.

Author of Two Bestsellers
In addition to articles and media commentary, Ron has authored books that solidify his status as a thought leader. Most notably, he wrote Fight the Feds: Unraveling Federal Criminal Investigations, an eye-opening book that serves as a roadmap for citizens and professionals to understand and defend against abusive federal tactics. In this Amazon-available guide, Ron pulls back the curtain on how federal agencies build cases—and how to protect one’s rights through each stage of an investigation. He exposes the “dirtiest tricks” the government can deploy and empowers readers with knowledge to fight back. He is also the author of Truth & Persuasion: In the Digital Revolution, a work examining how influence is crafted and contested in modern society.

Protector and Counselor
Ron’s leadership extends to the business side of healthcare law as well. He is the President of Safe Harbor Healthcare, a consulting firm that advises hospitals and medical practices on compliance and internal investigations. Through CCG Healthcare, Ron helps organizations proactively avoid running afoul of federal regulations. He and his team conduct audits, devise compliance programs, and guide clients in responding to government audits or subpoenas. In recent years, Safe Harbor Group (SHG)—which Ron formed with top healthcare experts—has prevented over $550 million in government overpayments, fines, and forfeitures for providers by catching issues early and fixing them. This preventative work aligns with Ron’s philosophy that the best win is the crisis that never occurs. It also means that when clients do call him after an investigation has begun, he often knows the administrative terrain well enough to negotiate effectively with agencies like the DEA, FBI, HHS, and FDA. Whether writing a book, appearing on television, or consulting on compliance, Ron’s goal is consistent: to protect individuals and professionals from unjust government action before, during, and after any legal battle.

He spares no effort in challenging the government’s case—filing bold motions to expose investigative missteps, rigorously cross-examining federal agents and expert witnesses, and ensuring that every legal avenue (suppression, dismissal, jury instruction, etc.) is fully explored. This exhaustive approach often leads to uncovering prosecutorial weaknesses that less dedicated attorneys might miss. Ron has a proven ability to flip the script, turning a complex case into a story of government overreach or reasonable doubt that jurors readily understand.
Professionalism, Values and Ethics
At the same time, Ron never loses sight of the human story behind each case.

Ron takes the time to truly know his clients and their values, so he can tell their story convincingly in the courtroom.

He is driven by a deep sense of duty—a continuation of his Marine Corps ethos—to protect the innocent and hold the government to its burden of proof. In Ron’s view, defending a client is serving a cause greater than oneself: it’s upholding the constitutional ideals of due process and the presumption of innocence. This passion for justice has not gone unnoticed. In addition to the judge who lauded Ron’s talent, many others have offered glowing testimonials. Fellow attorneys refer cases to him with confidence. Former clients send grateful referrals, noting how Ron saved their careers or kept their families together.
