In-Person vs Telehealth in California

The clinics in this directory are in-person obesity-medicine, endocrinology, and bariatric-surgery practices — a good fit if you want a local relationship, have complex needs, or need in-person documentation for insurance. Many California residents instead use a licensed telehealth provider that ships compounded semaglutide or tirzepatide directly to their address. Featured California telehealth partners:
