About me

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.

Kidder belongs to the American Society of Clinical Oncology and American Society of Hematology.

      We came to a pivotal point in my treatment. Dr Kidder provided the pros and cons and then discussed the options with me and my family members (also on the video appointment), but always allowing the final choice to be mine. We can't say enough about how great a doctor and person he is.

      As frightening as this whole cancer thing has been, Dr. Kidder has made it easy and enjoyable as crazy as that may sound. I leave our meetings feeling better after hearing his thoughts on test results, we have an action plan for what's next, and my appointments are scheduled by his awesome staff. With each encounter at UCSF I leave feeling lucky to have such good care from some really good people.
