Profile

What to Know

Signature approach

Hyman's clinical frame is functional medicine: nutrition, inflammation, hormones, gut health, toxins, and metabolism are read as connected systems. At Function, that lens appears in the broad biomarker panel, root-cause interpretation, and food-and-lifestyle guidance members can discuss with their own clinician.

What sets them apart

  • Functional medicine at health-system scale. He founded the Cleveland Clinic Center for Functional Medicine and helped bring the model into a major academic health system.
  • Large public education platform. Sixteen New York Times bestsellers and The Doctor's Farmacy make him one of the most recognizable physicians in preventive health.
  • Dual training frame. ABFM family-medicine certification plus IFMCP training connects conventional primary care with functional medicine.
