For over three decades, Chapman Law Group has built its reputation on the sole principle that healthcare professionals deserve skilled, committed, and relentless legal representation. From its founding in Michigan to its expansion in Florida, California, and across the nation, the firm has grown alongside the needs of the healthcare industry. Along the way, the firm assembled a team of attorneys who shared that same commitment. A commitment that started from the top.
Founding Shareholder, President and CEO Ronald W. Chapman Sr. has spent 38 years practicing law, 36 of which have been dedicated exclusively to the representation of healthcare professionals. Joined by Shareholders David B. Mammel, who has spent nearly three decades helping individuals and families protect what they have built through estate planning and administration, and Summer McKeivier, a nationally recognized federal trial attorney who has represented clients in high-stakes healthcare fraud and government investigation matters across almost every U.S. District Court in the country, the firm has always been anchored by attorneys who lead with conviction. Today, that team grows even stronger with the elevation of six attorneys to Shareholder.
Their collective experience spans licensing and regulatory affairs, healthcare fraud and other federal criminal matters, corporate transactions, healthcare compliance, civil litigation, and beyond. Sara A. Bazzigaluppi, Jonathan S. Meltz, Juan C. Santos, L.L.M., Aaron J. Kemp, Jonathan C. Lanesky, and Devlin K. Scarber each bring distinct expertise that further strengthens the firm’s ability to serve healthcare professionals across the country.
Sara A. Bazzigaluppi is a Florida based attorney who has built her practice around defending healthcare professionals when their licenses and livelihoods are on the line. When a complaint is filed against a physician, nurse, pharmacist, dentist, or other provider, the clock starts ticking, and Sara knows how to get ahead of it. She works with clients facing investigations and disciplinary actions before the Florida Department of Health and its Boards, proceedings brought by the Agency for Health Care Administration (AHCA), matters involving the Centers for Medicare and Medicaid Services (CMS) and the Office of Inspector General (OIG), and hearings before national certification bodies. Whether the goal is resolving an investigation before a formal complaint is ever filed, challenging an emergency suspension, or fighting a credentialing, peer review, or NPDB report, Sara approaches each case with a willingness to identify procedural flaws, challenge regulatory overreach, and raise legal arguments that others might not think to pursue.
With nearly 30 years of federal trial experience, Jonathan S. Meltz has built a reputation as a formidable defender of healthcare professionals facing high-stakes federal investigations and prosecutions. Whether a physician is facing a grand jury target letter, a federal search warrant executed at their practice, or an indictment alleging healthcare fraud or Anti-Kickback Statute violations, Jonathan is the trusted advocate healthcare professionals turn to when their license, reputation, and future are at stake. With a record of close to 100 jury trials and numerous not-guilty verdicts in complex federal cases, he has demonstrated time and again that the government’s cases are not always as airtight as they appear. His clients have faced scrutiny from the DOJ Healthcare Fraud Strike Force, the HHS Office of Inspector General, the FBI, and the DEA, and Jonathan knows how to fight back at every stage, whether that means challenging the government’s loss calculations, negotiating before charges are ever filed, or taking a case all the way to verdict. His track record has earned him recognition as a 2024 Top-Rated Super Lawyers White-Collar Crimes attorney, a Martindale-Hubbell AV Preeminent rating, five nominations for appointment as a Miami-Dade County court judge, and national media attention through appearances on South Florida television news stations, A&E Network’s After the First 48, and CNN’s Court TV.
For healthcare businesses, staying ahead of government scrutiny often begins with strong regulatory compliance, and that is where Juan C. Santos, L.L.M. has built his practice. He advises physicians, medical groups, pharmacies, DME companies, and other healthcare entities on a wide range of regulatory and compliance matters, including Anti-Kickback Statute and Stark Law analysis, HIPAA compliance, Medicare and Medicaid audits, False Claims Act matters, and DEA-related issues. On the transactional side, he guides clients through the acquisition and sale of healthcare practices, helping them structure deals that can withstand regulatory scrutiny. Fluent in both English and Spanish, Juan brings a practical, business-minded approach shaped by his experience working with medical groups, hospitals, and health maintenance organizations before joining Chapman Law Group.
When a complaint is filed with the Michigan Department of Licensing and Regulatory Affairs (LARA), a healthcare professional’s license, reputation, and livelihood can quickly be placed at risk. For more than 20 years, Aaron J. Kemp has dedicated his practice to defending providers in exactly those high-stakes situations. As Chairperson of Professional Licensing and Regulatory Affairs for Michigan, Aaron understands how quickly a licensing investigation can escalate from an initial complaint to a formal administrative action, disciplinary hearing, or even the loss of a provider’s ability to practice. He represents physicians, nurses, dentists, pharmacists, and other healthcare professionals at every stage of the process, whether resolving matters during the investigative phase before a formal complaint is filed, defending against disciplinary actions, or handling credentialing and NPDB issues that can impact a provider’s career across state lines. His work has drawn recognition from NBC News, The Washington Post, and The Associated Press, and he was honored as a 2019 Lawyer of Distinction in Healthcare Excellence Law.
With more than 25 years of experience, Jonathan C. Lanesky has built a practice focused on helping healthcare professionals and organizations handle the legal, regulatory, and operational challenges that arise throughout the life of a healthcare business. He advises physician groups, ancillary service organizations, and other healthcare businesses on corporate structuring, operational strategy, and mandatory reporting obligations. When licensing investigations arise, he represents providers before LARA and other regulatory bodies, and when reimbursement and compliance disputes escalate into CMS audits, third-party payer audits, wound care audits, or related enforcement actions, he is equally prepared to advocate aggressively on their behalf. His certification as a Resident Producer through the Michigan Department of Insurance and Financial Services further reflects the depth and versatility of his experience across the healthcare industry.
Devlin K. Scarber is a Detroit-based civil litigator who has spent more than 20 years defending healthcare professionals and facilities against medical malpractice, professional negligence, and complex civil litigation claims in state and federal courts. What sets Devlin apart is where he started. Having spent the early part of his career on the plaintiff’s side of medical malpractice and negligence cases, he developed a firsthand understanding of how opposing counsel builds a case, what arguments they lean on, and where their strategies are most vulnerable. That perspective has made him a more effective defense attorney, one who knows how to challenge standard of care arguments, counter negligence claims, and present a compelling defense case to a jury. His practice also extends to No-Fault personal injury protection cases, where he has successfully argued for proper reimbursement on behalf of healthcare providers. Outside the courtroom, Devlin serves as a tutor and mentor in the Michigan Bar Passage Program and volunteers at criminal record expungement fairs in Metro Detroit.
The healthcare industry is one of the most heavily regulated in the country, and the professionals who work within it deserve legal representation that reflects the complexity of what they face. With the elevation of these six attorneys to Shareholder, Chapman Law Group reaffirms its commitment to building a team that can meet healthcare professionals wherever they are. So, whether that means defending a license, fighting a federal indictment, navigating a corporate transaction, setting up a compliance plan for your practice, or litigating a qui tam case, Chapman Law Group is a firm built from the ground up to fight for you. These are not just accomplished attorneys; they are advocates who have dedicated their careers to protecting the people who keep the healthcare system running. Chapman Law Group congratulates these six attorneys on their accomplishments and gladly welcomes them as its newest shareholders.
