    I don't understand how or why I got off on the wrong foot with Dr Denmark but I felt that he did not ask open ended questions, was confused about the details I was providing and had seemingly irrelevant points of contention when I was narrating my history. For example, I said- "last year, I had this test". He corrected me to say "18 months ago". Now I understand that it is more accurate to say 18 months but as a patient, when I'm freely sharing my history and the relevant details, correcting me in this manner seemed irrelevant and distracting. Additionally, he seemed fixated on understanding why my previous providers prescribed a medication/why they ordered a certain test. Despite telling him that I do not know, he seemingly berated me, saying that if he were a patient, he would want to know why a certain test were ordered. Such an attitude really disrupted the patient-doctor relationship I intended to have and made me feel like I wasn't there to receive care but rather be put on trial. [redacted] Eventually, I did confront him and his attitude changed with multiple attempts at humor and lightening the situation but I feel the damage had been done. [redacted]

    I often saw another person than Dr. Denmark, and she was fine. But regulating the medication at home was difficult to get concurrence at the office since I talked to a receptionist who got the info to a nurse who would then call me and then talk to the doctor. By the time I got approval, it was many hours later. I ended on regulating my own medication at home.

Because I kept asking questions, he said, I can take a listen if you want. He just quickly listened to my chest. That was about it. I don't feel that he did a thorough job at all.
