I have nothing but good things to say about Dr. King, and everyone involved.

National Jewish Health PatientMay, 2016
very good experience so far

National Jewish Health PatientMay, 2016
this visit was a follow up on my condition. I told Dr King that it was much improved and it was decided that I was in charge now and it was up to me when and if I needed to come back in.

National Jewish Health PatientMarch, 2016
This was the best provider experience I've had in a very long time. It restored my faith in the medical profession.

National Jewish Health PatientFebruary, 2016
The last visit with Dr. King included discussions that themselves were tricky, such as with to get my hernia fixed ...not straight forward, so neither was the conversation and/or conclusions. These subjects aren't black and white, and the conversation and conclusion reflected that, which as a patient left me feeling still undecided, questioning, etc.... It's hard to answer these questions because subjects/conditions skewed.
