Dr. Ronald Primas

Ronald Primas, M.D., FACP, FACPM, DABIHM is the Founder and Chief Executive Officer of the Primas Center for Integrative Precision Geromedicine and Human Performance, a Manhattan concierge practice devoted to longevity, healthspan, and human performance.

A triple board-certified internist, longevity physician, and pioneer of the concierge medicine movement, Ronald has delivered precision-focused, prevention-first medical care to a discerning patient population for more than three decades. He has owned and led his Upper East Side concierge practice, Travelers Medical Center, since 1993, building a model of high-touch, relationship-based medicine that combines academic internal medicine with the emerging biology of aging.

Ronald’s clinical work integrates advanced diagnostics such as genomics, epigenetics, methylation-based aging clocks, microbiome analysis, telomere length assessment, and VO₂ max testing with targeted interventions including NAD+ optimization, fasting-mimicking diets, continuous-glucose-monitor-guided nutrition, mitochondrial support, and senolytic therapies. He is a clinical advocate for geromedicine, an emerging field that applies the biology of aging to prevent age-related disease before it manifests.

Board-certified by the American Board of Integrative Holistic Medicine, he blends Western and Eastern approaches, incorporating acupuncture, qigong, nutritional therapy, and circadian and ancestral-health principles into a whole-patient practice. A self-described biohacker and advocate of the quantified-self movement, Ronald tracks and applies his own biometric data through what he calls the “Primas Primal Protocol.”

Ronald serves on several scientific advisory boards in the longevity field. He is an Advisory Board Member of the Alliance for Longevity Initiatives (A4LI), a nonprofit advancing legislation and policy to extend healthy human lifespan, where he advises on legislative priorities, emerging biotechnologies, and national funding opportunities that support geroscience research and equitable access to next-generation therapies.

He also advises Aeon Biomarkers, an Austin-based company developing machine-learning-powered biological-age diagnostics and molecular biomarker panels, and Calibre Biometrics, which builds wearable breath-calorimetry technology for real-time VO₂, CO₂, and metabolic analysis used in performance medicine and longevity assessment.

Ronald is also a nationally recognized travel and tropical medicine expert, doubly credentialed in Clinical Tropical Medicine and Travelers’ Health through the American Society of Tropical Medicine and Hygiene and in Travel Medicine through the International Society of Travel Medicine.

He has been a frequent media contributor on emerging infectious diseases, from HIV, SARS, and MERS to Ebola, Zika, and COVID-19. In November 2002, Ronald recognized and diagnosed New York City’s first case of bubonic plague in more than a century, identifying the classic “bubo” in a visiting couple, sending them to Beth Israel Hospital, and alerting the CDC and city health officials at a moment of heightened bioterrorism concern. The case was documented in the CDC’s Imported Plague — New York City, 2002 report.

Ronald holds an academic appointment as a Clinical Instructor of Medicine at the Icahn School of Medicine at Mount Sinai and has served as an attending physician in the Department of Medicine at Mount Sinai Hospital and the former Beth Israel Medical Center. He is a Fellow of the American College of Physicians and a Fellow of the American College of Preventive Medicine, and is board-certified by the American Board of Internal Medicine.

Ronald earned his M.D. from the American University of the Caribbean School of Medicine in 1986. He completed his internal medicine residency at NewYork-Presbyterian Brooklyn Methodist Hospital in 1990 and a residency and fellowship in Preventive Medicine and Public Health at the UC San Diego School of Medicine in 1992. He earned his Bachelor’s Degree of Science in Biology from Binghamton University in 1982.

Over his career, Ronald has received numerous honors, including the American Academy of Home Care Physicians House Call Doctor of the Year Award in 2002 and the AMA Physician Recognition Award. He is often likened to a modern-day Marcus Welby, M.D., and has been recognized as a Castle Connolly and U.S. News and World Report regional Top Doctor in Internal Medicine, listed in the Guide to America’s Top Physicians, and named among the top physicians in concierge medicine.

He is a member of The Explorers Club, the New York-based society for scientific exploration, and a contributing consultant on travel health to outlets including National Geographic Traveler, Self, Health, and Forbes.
