Dr. Jennifer Ron is board-certified in both Emergency Medicine and Integrative Medicine, bringing 25 years of emergency medicine experience to whole-person cancer care.

She is also the author of the forthcoming book, Integrative Medicine for All: A Physician’s Healing Cancer Journey.

Patients who work with Dr. Ron receive the unique dual perspective of a cancer patient and a physician who spent 25 years practicing in some of the highest-stakes areas of conventional medicine. She brings that same rigor, along with the insight gained from her own cancer journey, to evidence-informed integrative cancer care.

Her goal is not to replace conventional cancer treatment, but to expand the tools available to patients, empowering them to create an inner environment not hospitable to cancer growth while becoming stronger, more informed, and more supported throughout their cancer journey.

Dr. Sajad Zalzala is a board-certified family medicine physician and one of the most recognized voices in longevity and preventive medicine in the United States. Over the past two decades, he has built a career at the intersection of clinical care and health innovation, with a particular focus on the therapies and interventions that science suggests can extend not just lifespan, but healthspan, the years lived in good health.

He is best known as co-founder and former Chief Medical Officer of AgelessRx, the first national telemedicine platform dedicated to prescription longevity therapies, which he helped grow to more than 50,000 active patients across all 50 states. Under his clinical leadership, AgelessRx introduced treatments including low-dose rapamycin, metformin, NAD+, and low-dose naltrexone to a broad patient population, and conducted the PEARL trial, one of the first prospective studies on rapamycin’s effects on healthspan in real-world aging adults. He has published more than ten peer-reviewed articles on geroscience, glucose optimization, immune health, and aging interventions, and has been featured in the Wall Street Journal, Scientific American, CNBC, and Fox News.

He was a finalist in the XPRIZE Healthspan competition, a global challenge attracting more than 600 teams, and is currently completing a book on the emerging science of longevity medicine.

Patients working with Dr. Zalzala gain access to a physician who has spent his career on the front lines of what preventive medicine can actually look like when it moves beyond routine checkups and into the biology of aging itself.

Dr. Jonathan Abel is a board-certified family medicine physician with more than two decades of experience across primary care, urgent care, hospital medicine, occupational medicine, and direct primary care. His career has taken him into diverse communities and healthcare environments, from nearly three years of medical service at Memorial Christian Hospital in Bangladesh, to serving Native American communities through the Indian Health Service, to caring for Veterans through the VA Healthcare System.

Those experiences have shaped Dr. Abel’s grounded, patient-centered approach to medicine. He believes good care begins with listening, honesty, and trust. Patients should feel that their physician has their best interests in mind, is willing to explain the reasoning behind recommendations, and is comfortable having open conversations about what matters most to them.

Back in the U.S., Dr. Abel has continued his work in primary and direct primary care settings. In 2025, he completed coursework and training through the Institute for Functional Medicine, including Applying Functional Medicine in Clinical Practice (AFMCP) and the Advanced Practice Module (APM) for GI, adding a root-cause and whole-person framework to his broad clinical foundation.

At Metabolic Care, Dr. Abel brings this practical clinical experience to conversations around metabolic health, prevention, health optimization, and supportive care. His goal is not to promote a product or a one-size-fits-all answer, but to help patients make thoughtful, informed decisions about their health with integrity, clarity, and evidence as the foundation.

Dr. Frank Salvatore is a board-certified urologist and surgeon with three decades of experience across the full spectrum of urologic care. A graduate of Georgetown University School of Medicine, he completed his surgical training at Georgia Baptist Medical Center before earning his urology residency and chief residency at Tulane University School of Medicine in New Orleans.

Over a 30-year career in New Jersey, Dr. Salvatore built a reputation as both a skilled proceduralist and a practice builder. He founded Skylands Urology Group in 1996, which he led for 20 years, and served as a founding board member of both The Stone Center of New Jersey and a specialty surgical center in Sparta. His clinical subspecialties include minimally invasive surgery, laparoscopic and perineal procedures, urologic laser surgery, lithotripsy, and urodynamics.

What sets Dr. Salvatore apart on a metabolic health team is the range he brings beyond surgery. In 2016, he earned board certification in Integrative Holistic Medicine, reflecting a long-standing belief that optimal outcomes depend on treating the whole patient, not just the diagnosis. He has been a Fellow of the American College of Surgeons since 1998 and maintains active membership in the American Urological Association and several other professional societies.

Patients working with Dr. Salvatore can expect a physician who combines rigorous surgical training with a genuine interest in how lifestyle, metabolic health, and integrative approaches can improve outcomes before, during, and after medical treatment.
