Dr. Natalie A. Marshall is a medical oncologist who cares for patients with breast and lung cancer using chemotherapy, targeted therapy and immunotherapy. She also works with her patients on modifying their habits with the goal of making their bodies less hospitable to cancer growth. This includes instruction and encouragement on diet, sleep, stress reduction and exercise, including strength training. It is important to her to let patients know how lifestyle modifications can lower the risk of cancer recurrence. She serves as medical director of the UCSF – John Muir Health Cancer Center in Berkeley.

Throughout her career, Marshall has been helping patients participate in clinical trials to evaluate cancer treatments, starting at Yale New Haven Hospital as a fellow and faculty member in the breast care unit and stem cell transplantation program, and later working in New Mexico and California in community oncology (which seeks to provide quality cancer care close to where patients live) and private practice. At New Mexico Cancer Center for more than a decade, she ran the state's only program that conducted autologous stem cell transplantation (replacing diseased or damaged cells with healthy blood stem cells from the patient).

Marshall earned her medical degree at the University of Texas Medical Branch at Galveston. She completed a residency in internal medicine at the University of New Mexico Hospital, followed by a fellowship in medical oncology at Yale New Haven Hospital.

Marshall has received numerous honors, including a people's choice doctor award in New Mexico in 2010; a Top Docs award from Albuquerque The Magazine in 2009; inclusion in Castle Connolly's Top Doctors in San Francisco in 2015; and induction into Leading Physicians of the World (a print and online resource) in 2017.

Outside of work, Marshall is a jazz musician and lyricist who performs in the Bay Area whenever she can. She is also a masters division Olympic weightlifter, avid hiker and gardener, mother and wife. These activities bring balance and compassion to her role as a doctor.

    May 03, 2025
    I have referred Natalie to other women. I can't say enough about how lucky I feel to have her on my team. I have had a rather complicated health history and journey. She is on top of all of it and has encouraged and guided me through the rough patches. She listens so completely and lets me express my angst and also acknowledges my very real efforts to get and stay well despite all of the diagnosis. I believe she truly sees me as a human and a woman and that is such a gift. I am a pretty eclectic character who has faced a lot of chanllenges and she has really helped me see the long game. I can't believe my good fortune in landing her as my breast oncologist. She is very special.

    Jun 19, 2024
    Dr. Marshal is smart, experienced and caring !!! She's already thinking about what upcoming clinical trials I might benefit from.. I appreciate this from her due to the fact that black women such as myself die from breast cancer at a higher rate than other groups of women. In addition, she empowers me to think about the things I can do to reduce the recurrence of BC such as staying focused on my diet and exercise.
    Jun 18, 2024
    Dr. Marshall took time to discuss my current medications, and to communicate the estimated time that I would continue taking them, as well as suggesting a drug trial that she thought I would be a good candidate for. She showed concern for any side effects that I am experiencing form the medications. She advised me on what to watch for in general for cancer reoccurrence and regarding a red spot on my skin that I asked her about, and showed compassion for all that I have been through. I felt like I was her only patient, even though I know that Is not anywhere near the truth.

    Dr. Natalie Marshall is knowledgable, confident, understanding, and replies to inquiries on myChart promptly.. I don't have a perfect word to describe her but she Is just awesome! When she first saw me, I was very weak, sick, deteriorating... She of course had seen and studied all the pet ct scans, biopsy, my medical history and treatments before she saw me for the first time. She explained to me and family member what's wrong with me, her analysis/diagnosis, plan of treatment, and other things to expect.. That was ~months ago. I am feeling better at this time. My friends and family notice the big improvement. One friend who was recently diagnosed with another form of cancer asked me to ask Dr. Marshall for oncologis names and she promptly gave to me.
