    Dr Kobashi is INCREDIBLE. 5 is not high enough.
    Oct 12, 2025
    He was very rushed and seemed annoyed right away when I said I had some health questions which he said I should have listed for his nurse ahead of time. How would I know that? He was more focused on typing while I spoke rather than hearing my concerns, and of which he had very little comment. I only see him once a year and expect a little more interest. It was probably the worst appointment I've ever had with any doctor.

    Dr. Kobashi is the best doctor I have ever had in my (75 years old) life. He is patient, supportive and attentive, and he unerringly asks additional questions that help me add missing details or other information I may have omitted. And he is brilliant--far and away The Best. UCSF - don't you dare let anyone hire him away!
