  • Dr Keiser is an amazing doctor who is not only up to date on scientific info but understands the emotional aspects of being a doctor. In the oncology space this is very important
    Attentive provider and staff
    Very attentive to my particular problem.
    He takes time to explain things and to help you understand what's going on.
    Dr Keiser is going to experiment with my pill for my blood platelets. He finally listened to my problem with low red blood cells and causing me to be anemic.
