      Dr. Natsuhara is the best physician that I have had at UCSF. She is very professional but also very personable. She remembers her patients and is well prepared to discuss issues, or the lack thereof. She is extremely knowledgeable and explains things in a way that I can understand what is going on. Dr. Natsuhara always listens to my concerns and also understands what I want regarding my cancer care. She is such an asset to the Oncology program at UCSF. You need more doctors like her. She is very empathetic.

      Excellent. Highly interactive. I think I just look for answers that can't be known right away.
