    The care provider, the doctor is absolutely wonderful. I have recommended him to other people, as well as all the service that I get when I go there. Everybody's wonderful.

    Dr. Yang is always a pleasure to work with on this and he was particularly well prepared this time because I had some other, I think, unrelated health issues and he seemed to know quite a bit about them. So he read my record and was quite up to date. So I appreciated that.

    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.

    Dr. Yang was extremely thorough and paid meticulous attention to my past medical history as far back as the last 20 years. I feel very comfortable with him and he has gone above and beyond to make sure that I understand the complexity of my anemia. I would highly recommend him to anyone and am completely satisfied with his care.

    Dr. Yang was fantastic. He clearly and carefully explained my red blood cell situation in a way that i had not been able to understand. Other providers, who are not specialists in this area, had not been able to do that for me. Dr. Yang also said he would review future blood tests to make sure they are as he expects and are on track.

    My visit with Dr Yang was a detailed explanation, using the last twelve years lab results as evidence, of why I did not need to see a hematologist. He was direct, articulate, and convincing. Of course I did not refer myself to hematology, my PCP did, and little of what he said shed light on the symptoms I have experienced over the last few months. Dr Yang was right of course. He could have delivered the same information in an email to my PCP.

    I was being seen by a different oncologist and came here looking for a better experience. Dr. Yang was amazing in every way. He studied my chart prior to the appointment and did a rundown before we discussed a treatment plan. He was informative of each plan of action so I could make the best decision of how to move forward. He was humble and supportive of the entire nursing team that he works with. I went from a horrible experience at a different practice to one that would be almost impossible to top.
