In matters of medicine and the law, few specialties require the precision and deep clinical understanding that nephrology demands. At the intersection of kidneys, complex disease processes, and legal interpretation stands Griffiths Renal Consulting, led by nationally recognized nephrologist Kevin O. Griffiths, MD, MPH. Serving clients nationwide, this consultancy provides trusted, evidence-based insights in cases where renal health is central to the legal question.
Experience That Builds Confidence
With more than two decades of clinical and academic experience, Dr. Griffiths is an experienced kidney expert whose reputation extends well beyond the courtroom. He is a five-time recipient of the Castle Connolly Top Doctor award, including the prestigious Top Black Doctor recognition in 2023. He has also been named America’s Top Physician in Nephrology by the Consumer Research Council of America and one of the “Top 10 Nephrologists” by the American Registry.
As a kidney expert witness, Dr. Griffiths offers articulate, medically sound opinions rooted in up-to-date practice. His ability to translate complex renal issues into courtroom-relevant insights makes him a valuable resource for legal teams seeking clarity on chronic kidney disease, dialysis, medication management, and transplant complications.
A Trusted Voice in Nephrology
Dr. Griffiths is not just a clinician—he’s a respected voice in shaping the future of kidney care. He is a Fellow of the American Society of Nephrology (ASN) and was hand-selected to serve on several of the society’s most important committees, including the Practicing Nephrology Group, the Nephrology Diversity and Inclusion Work Group, and the Workforce and Training Committee.
This level of national leadership underpins the credibility he brings as a nephrologist serving in an expert witness capacity. His background includes academic appointments, quality improvement leadership, and extensive clinical care—all of which allow him to assess the nuances of standard of care and patient outcomes.
Hypertension and Beyond
Hypertension—both as a cause and consequence of kidney disease—is another key area of Dr. Griffiths’ expertise. As a recognized hypertension specialist, he offers insights into the long-term effects of elevated blood pressure on renal function and cardiovascular health. These insights are particularly valuable in medical malpractice, personal injury, and disability cases involving kidney damage or uncontrolled hypertension.
