    Never saw this Dr its very upsetting to wait a long time for an appointment and then only see a P A when waiting to finally see a Dr and then not made me feel like my issue wasnt important enough for anyone to care it simply was just push the patient off from bugging the primary care cause what was treated I feel was something my primary care dr could have taken care of right away cause we had discussed doing these things at a prior visit

    He is friendly, caring and very aware of all my concerns.

    His explanation of my condition and the stability of my lab results were easy to understand and how he emphasized the important results and how they affected my overall health

    Dr. said all of 25 words when he finally came into the room. No exaggeration. I mostly dealt with the PA/Nursing assistant. The appointment felt rushed, and secretive almost like there was a bias because I had called in a few times to get my appointment moved up sooner. When I tried to ask a question about the lab markers, I was met with the phrase "don't even go down that route" as if my questions were annoying or not warranted. I've had pretty good experiences at Univ of Utah. This wasn't one of them unfortunately. I mean I'm happy I don't have anything wrong with me I supposed from a hematology standpoint, but they could have at least shown me what the manual smear interpretation said. I feel like that is my right to know as a patient.
