About
Dr. Halland Chen trained at the University of Miami's Honors Program in Medicine, graduating with Honors in Research Distinction. He then completed a Fellowship in Interventional Pain Management at Albert Einstein College of Medicine in New York City. He holds dual board certifications in Physical Medicine and Rehabilitation and in Pain Medicine.
Dr. Chen founded Impact Health Medical and specializes in functional medicine, longevity, interventional pain management, and peak performance. He conducts research on cellular health and mitochondrial efficiency, and experts in the field recognize him as a leading authority on NAD (Nicotinamide adenine dinucleotide). His research extends to stem cell technologies, joint cartilage regeneration, and reducing pain in knees, shoulders, and hips. He authored numerous scientific publications and contributed a chapter to a Pain Medicine textbook on holistic medicine dosing and techniques. Dr. Chen applies methylation testing to determine biological age, a method he used publicly in the Natalia Grace case. He serves as a keynote speaker at international health conferences, including Wonderland 2023 and Eudemonia Summit 2024, where his topics covered longevity, personalized bio-stacking, and cellular health. He travels globally to build community and stay at the frontier of research-backed discoveries in modern medicine.
