Dr. George Kessler, D.O., has practiced integrative and functional medicine for more than 40 years. His focus is simple: helping you find, maintain, and optimize your health through personalized, whole-body wellness — delivered one-on-one through a virtual practice on a secure, encrypted medical platform.
The Practice
Dr. Kessler is board-certified in family medicine (AOBFP), Assistant Professor of Family Medicine in Medicine at Weill Cornell Medical College, and a consulting physician at Hospital for Special Surgery in NYC. He brings the entire toolbox to the table — pharmacology when it helps, and just as often nutrition, movement, sleep, hormones, supplements, stress, and the doctor–patient relationship itself — to help you maintain wellness and balance in your body.
He keeps the practice intentionally small so he can be very familiar with each patient, very hands-on, and personally available.

A plan built around your biology, your history, and your life — designed to find, maintain, and optimize your health, not chase a single label.
Visits happen on a secure, encrypted medical platform. An intimate, relaxed setting with no interruptions — Dr. Kessler hears the whole story.
Help navigating a complex diagnosis, second opinions, and care coordination — one physician thinking about the whole picture.
What We Work On
If your concern isn't listed, please ask. Many patients arrive after a long workup elsewhere — a fresh, integrative second opinion often reframes the path forward.
