National Jewish Health PatientFebruary, 2023
Dr. King spent a great deal of time not only following up with my last visit, but explaining the upcoming procedure in detail and calming my fears!

National Jewish Health PatientJanuary, 2023
Absolute best doctor at National Jewish. Extremely intelligent, while explaining complex diagnoses that come with this complex Cystic Fibrosis disease I deal with. Dr. King spent a solid hour with me, going over my concerns/questions in a way which not only did I understand but also felt like he has my back and I'm not alone in this. Despite being the head of GI, I never feel like he's rushing me away or his time is too invaluable. That is a rare thing these days and I greatly appreciate his authenticity.

National Jewish Health PatientJanuary, 2023
