Amazing experience with Dr. King! He spent more time with me than any other specialist. He made me feel comfortable and heard all while giving me a game plan on improving my functional issues. He also followed up with me on the same evening after hours to put my mind at ease about a past CT scan that I had questions about. Absolutely the best experience I have with a specialist! Thank you!

[PHI redacted] I could not have asked for a more professional and complete physician's consultation.

National Jewish Health PatientMay, 2018
Dr. King was excellent at helping us understand my disease. Some stuff I had never heard of opened my eyes to problems that I wasn't aware of and never been tested for. So in my opinion Dr. King is excellent.
