About me

Dr. Natalie A. Marshall is a medical oncologist who cares for patients with breast 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.

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.

      I wish I'd had a way to write some of the really important information that Dr Marshall offered to me. Or that some of it was printed out as she told me.

      Dr Marshall is an outstanding physician-clear and helpful communication, good listener, knowledgeable, compassionate, empathetic and kind. She answers my questions at a level I understand and has patience (I always have lots of questions for MDs). I feel well-cared for by Dr Marshall and her team, and always feel that I'm involved in decisions about my care. I have less stress about my condition under her care. She's awesome!
