    Dr. Kidder was kind and thoughtful. He took time to get to know me as we talked. The discussions of my disease were very understandable. He answered questions I had from reading about it and when I asked for clarification of something he said. He had obviously read my files explained some thingsmy initial oncologist did not. He was not in a hurry and focused his attention on me which I really appreciated. He is a specialist in the rare type of cancer I have which was so helpful. He is a huge asset to your program.

    Dr. Kidder is a credit to UCSF Health. As a gastrointestinal oncologist at the UCSF Helen Diller Family Comprehensive Cancer Center focusing on Neuroendocrine Tumors Dr. Kidder is one of the best In his field. Since September 2020 Dr. Kidder has been the coach directing the team providing me with the best medical plan and care possible. What is remarkable that Dr. Kidder's accomplishment is happening with myself being 2000 miles away on Oahu Hawaii. UCSF Health has achieved bringing world class medicine to patients not able to travel due to COVID.
