About
At Extension Health, a six-physician team delivers precision longevity and performance medicine across two New York City locations. The West Village clinic at 160 7th Ave South has anchored the practice since Dr. Jonathann Kuo founded its predecessor, Hudson Health, in 2010. A second location in Midtown recently opened, housing the practice's advanced imaging suite including the Omega360Scan 3T MRI full-body system.
Dr. Kuo and his team have treated more than 50,000 patients and performed over 140,000 procedures. The clinical roster spans anesthesiology, emergency medicine, gastroenterology, nephrology, critical care, and psychiatry. Specialists include Medical Director Dr. James Salway, gastroenterologist Dr. Mishal Reja, sports medicine director Dr. Nick Copeli, interventional psychiatrist Dr. Salim El Sabbagh, and longevity specialist Dr. Kathleen Léger. Together they run programs spanning peptide therapy, therapeutic plasma exchange, EBOO ozone therapy, hyperbaric oxygen, regenerative orthopedics, hormone optimization, gut health, and women's health. Membership tiers range from a two-day executive reset to an invitation-only Superhuman program capped at 25 members, personally overseen by Dr. Kuo. The New York Times, Wall Street Journal, and New York Post have all covered the practice.
