Dr. Greenberg entered the exam room with enthusiasm and a smile. He already had sent my requests for medication refills to the pharmacy I go to before he came into the exam room. I was free to go sooner than expected.

I had a hard time talking to him. He seemed rushed when he came into the room. I told him that I needed help with my pain. I didn't say anything else because I usually start to tell a lengthy medical history with all of my symptoms. He was annoyed by my short answer as he asked for more information. I tried to talk but I was frozen. I told him that I had expressive aphasia and I was trying to find my words. I can't remember much about what I said about my health. I think that he's a good doctor and he complimented Gerald Loy, NP for his comprehensive blood panel that was ordered and Dr. Greenberg ordered a couple more blood tests to determine inflammation which made me feel like I was receiving care.

My primary left. Optum botched an appointment request for a annual physical exam. Dr. Jack was available for a same-day appointment. He will not be my primary. Seemed very busy, but did see me twice and provided a diagnosis, for which I'm grateful.

Dr. Greenberg was attentive to my physical concerns and very importantly dealt with a physical issue that related to my appointment on that particular day. I appreciated his expertise very much.

The length of time he spent with me, less than 5 minutes. His attitude toward me was one of ,I'm in a hurry, I need to get to my next patient. He didn't talk about getting a mammogram, bone density test, or go over my recent labs. He said he wouldn't refill my compounding medication with no explanation why he wouldn't. As he flew out the door, he said, your labs are fine.
