    2026-07-02

  • First visit with Dr. Imbrie. I felt very comfortable talking with him. He is very knowledgeable and professional. He explained everything so we could understand. He listened carefully to our questions and concerns. I feel extremely fortunate to have him on my care team.

    2026-07-01

    2026-06-30

  • Dr Imbrie took the time to listen too and answer all of our questions. We left much reassured as to my condition.

    2026-06-14

  • Professional, knowledgeable and thoughtful.

    2026-06-06

  • I would have liked if the provider viewed the imaging and medical history before I was in the room or at all

    2026-06-04

  • This appointment was for a second opinion. The result is by having switched to this provider from the prior one . I think that says it all.

    2026-06-03

  • Dr. Imbrie listens and explains exceptionally well.

    2026-06-03

  • Dr. Imbrie was very empathetic. He was a good listener and I felt like he really cared about my health. I would highly recommend him.

    2026-06-03

  • Dr. Imbrie took the time to locate additional information regarding prescription options available to me and provided me with a clear explanation.

    2026-06-03

  • While Dr. Imbrie was somewhat personable, he contradicted information that my regular cardiologist (who I trust more than almost any other doctor I've ever seen) has explained to me, which made me hesitant. Then he basically said that the test he would do would prove that I didn't have a condition that several other doctors believe I may have the early stages of, so right from the beginning he was more or less dismissing mine and my doctors' concerns and saying I didn't have something without having even done the test yet. And then when he was explaining how the test was administered, he was making decisions that concerned me, and did not make me feel comfortable having him do the test. He's probably a great doctor for other people with other conditions, but he was not a good fit for me.

    2026-05-31

    2025-09-26

  • Dr Imbrie has always listened, explained and understood what my concerns are. I felt bad because when I went into the office and saw the sign saying he was behind. It can be viewed as negative. Sometimes us older people need time to understand or need something unexpected. Why else would a doctor run behind, other than caring for their patients? It's not like they're playing cards! I'm sure if you were the patient, you'd want to be treated like that.

    2025-09-22

    2025-08-20

  • He showed an interest in my comments and/or questions about other aspects of my life, so I felt more like he really cared about me as a whole person, not just about a heart.
