Fontaine MD
Fontaine MD is a preventive and longevity practice in the Torrey Hills part of Carmel Valley, built on Dr. James Fontaine's stated principle that if it isn't measured, it isn't managed. Every Healthy Aging consultation opens with a medical history, body composition analysis, a comprehensive lab panel and a carotid intima-media thickness scan. Hormone therapy and a full aesthetics menu sit alongside.
