Extension Health is an interventional longevity practice with clinics in the West Village and Midtown East. Diagnostics span DEXA, VO2 max, metabolic rate, biological-age and toxin panels, and 3T full-body MRI through an imaging partner, alongside on-site therapies including therapeutic plasma exchange and hyperbaric oxygen. Care runs as a membership. People come here for advanced and emerging longevity care.
