    I really like the fact that Dr. Gregory spent enough time with me gathering information about my medical history. He was keen on listening to my problems. I didn't feel rushed. He explained very deeply about the issues that I had and how to address it. I wish more doctors spent as much time and gave as much clarification. He has ordered labs for me to check on my thyroid periodically, which I truly appreciate. It was a challenge with my previous PCP. And he definitely has an ear with my need for supplements, so he also was very encouraging about it.

    Dr Gregory is awesome and I am very critical of the medical profession. I really feel they are sadists and ignore patient needs but don't get that at all from Dr Gregory.

    for my care provider, which is Dr. Oliver Gregory. I just wanted to say that he is absolutely exceptional. He takes his time to listen, go over my chart to discuss my blood work. He has recommended and has given me the option of whether I would like to see a physical therapist or I would like to see a specialist for any type of pain that I have. And he has given me the option, which I really like because instead of just sending me off for x-ray, he's given me the option. Also, I had the experience last year where I was going through rough patches, and Dr. Oliver immediately recommended that I see a therapist. And that did help a lot. So I really am appreciated that he took the initiative to schedule some help for me. And he did ask me.
