  • I can't even find the words to describe Dr. Yang. Exceptional doesn't even feel like enough. He called me twice on a Friday evening (same day as appointment) to share results, treatment plan and to tell me all medications had been called into pharmacy. He, by far, is one of the most caring and brilliant doctors with whom I've worked. He is the example of what every doctor should be striving for with exceptional care. I am very thankful to be in his care. I know he's going to carry me through a very frightening diagnosis. Thank you isn't even enough.
