    I love how well Dr. Obayashi explains everything.

    Experienced on Apr 03, 2020

    Dr Obayashi was very thorough and talked to me in depth about several of my questions and concerns. I liked meeting with him online because we talked face-to-face and he was focused on looking at me instead of looking at a computer. Although he couldn't do a physical examination, he understood my concerns and explained clearly what treatments were available to me. I liked that I received a video prior to my appointment that explained my condition and how to deal with it. I felt I could meet with Dr Obayashi with informed questions to ask and he re-emphasized what I learned in the video. Great way to learn and talk with my doctor to give me some background on my condition before I saw him.
