Dr. Wesley Kidder is a gastrointestinal oncologist with a special interest in colon and rectal cancers as well as neuroendocrine tumors (cancer cells arising from the endocrine and nervous systems).

Kidder studies the role that the gut microbiome – the microorganisms that live in the digestive tract – plays in the development and treatment of colon and rectal cancers. His research includes examining the changes in the microbiome that occur following treatment with oral chemotherapy.

After earning a master of public health degree from the University of Southern California, Kidder earned his medical degree at the George Washington University School of Medicine and Health Sciences. He then completed a residency in internal medicine at the University of California, San Diego, where he served as chief resident. He completed a fellowship in hematology and medical oncology at UCSF, where he also served as the chief fellow for his final two years.

    Good experience with Dr.Kidder. Kind listened and was informative. Just didn't get the results I was hoping from a teaching facility. Probably on me and guidelines.

    Considering what my healthcare provider had to inform me he was gentle and kind. I felt as though he was holding my hand through the screen. He is my main doctor and I think he is wonderful.

    Dr. Kidder is very friendly interested in his patients listens well and is thoughtful about his discussions.
    Oct 11, 2022
    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.
