Newtown Internal Medicine is a Langhorne, Pennsylvania-based integrative longevity and functional medicine practice led by Dr. Val Koganski, MD — a double board-certified internist and functional medicine physician who brings more than two decades of Bucks County clinical practice to a forward-thinking approach to healthspan extension. Dr. Koganski created the NIM Longevity Program — a comprehensive, whole-person longevity protocol grounded in National Institute of Aging research — to provide patients with something most primary care practices cannot: the early identification of age-related biological changes, and a personalized clinical roadmap to reverse or slow them before they become disease. Named a Top Doctor in Internal Medicine by Philadelphia Magazine every year from 2017 through 2025, Dr. Koganski has built Newtown Internal Medicine into one of the Bucks County region's most comprehensive destinations for patients who want proactive, evidence-based longevity medicine integrated with traditional primary care. The practice operates on a concierge medicine model, providing same-day appointments, telemedicine, and 24/7 direct physician access — the level of availability that true longevity medicine and complex care management demands. A Certified Peptide Therapy Practitioner, Dr. Koganski also integrates complementary modalities including acupuncture, biopuncture, homeopathy, and herbal medicine alongside conventional and functional approaches.

About the Physician

Dr. Val Koganski is board-certified by both the American Board of Internal Medicine (ABIM) and the Institute for Functional Medicine (IFM) — a dual certification that reflects his commitment to bridging rigorous conventional medicine with root-cause functional approaches. As a Certified Peptide Therapy Practitioner, he incorporates the latest in peptide-based regenerative medicine into his longevity protocols. Over more than two decades serving the Bucks County community, Dr. Koganski has developed the concept of “peakspan” — the idea that health optimization should aim not just for the absence of disease, but for maintaining peak physical, mental, and metabolic function across the lifespan. Philadelphia Magazine has recognized Dr. Koganski as a Top Doctor in Internal Medicine from 2017 through 2025 — a nine-year consecutive recognition that reflects his consistent clinical excellence and patient outcomes. His multidisciplinary team includes a Nurse Practitioner, a Registered Dietitian Nutritionist, and a Certified Health Coach, providing the wraparound support that comprehensive longevity programs require.
