National Jewish Health PatientOctober, 2020
Dr. King was outstanding. He listened and spent a good amount of time with me to help figure out what is going on with me. Thank you Dr. King!

National Jewish Health PatientOctober, 2020
Dr King is all around amazing! He doesn't make you feel rushed, he listens, he is knowledgeable, he doesn't make you feel just like a number but has empathy & understanding, he lets you be a part of your care & doesn't force things on you. He has a great bedside manner. Sometimes when there is nothing a doctor can do just hearing out their patients struggles & trying to have compassion & understanding makes a world of difference. The world could use more doctors like him!
