    Dr. Harris is excellent
    Sep 07, 2025
    Dr. Harris clearly has extensive evidence-based knowledge and chooses his words carefully to reflect evidence-based medicine. In the past at in-person visits, Dr. Harris spent extensive time with me to understand my issues. While my condition turned out to be minor over the course of being his patient, I still have outstanding health questions. In this visit, I wish Dr. Harris would have been more in the driver's seat. When I, the patient, am the one leading the conversation, I feel like I am limited by what I know. I do not know what I do not know. So I wish Dr. Harris asked more questions instead of me being the one to ask questions and prompt the conversation.

    Dr Harris's care has changed my life and enabled me to return to work full time, exercise weekly, and spend time with my friends and family. In addition to these benefits, he's the kindest doctor ever. He listens and is willing to investigate and adjust treatment. He communicates well about WHY he has chosen certain medications and why they are the most beneficial for my care, distilling research and evidence clearly and concisely.
