    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.

    Dr. Greenburg is one of the few doctors in practice that has the ability to find problems with your health that very few doctors have, at least in my experience.

    In spite of working for Optum, he provides excellent, compassionate care to his patients. He genuinely cares about them and their health. You should get his input about how to provide care to patients.
