What People Say(5)
Shilpa R.
Dr. Jang is a fantastic doctor, patient, kind, and a real listener. That said, after my last annual physical I got hit with an unexpected charge that I couldn't get resolved through Dr. Jang or Weill Cornell, so proceed with caution.
Priya P.
Dr. Joon was very professional and at the same time really easygoing. He agreed on what the issue was and gave me the right advice and medication. Happy to say I'm already seeing some improvement.
Michael P.
Dr. Jang is remarkably knowledgeable, thorough, and kind. He remembers the little details about my health, family, and work, and he takes time to answer everything I ask. Best doctor I've had.

I had a fantastic wellness visit with Dr. Jang and couldn't be happier with the care. From the moment I arrived he was warm, attentive, and truly invested in my overall health. He took the time to hear out all of my concerns.
