MSK nurse practitioner Odessa Williams

I have been in nursing for more than ten years, treating inpatient oncology patients, primarily those who have leukemia or lymphoma or who have had bone marrow transplants. I switched to the outpatient setting when I became certified as a nurse practitioner in 2014. I joined MSK in 2016 as a nurse practitioner who specializes in breast medicine. I deliver high-quality patient care with a multidisciplinary team to help implement care for patients undergoing active treatment as well as active surveillance.

I work closely with medical oncologists Andrew SiedmanMark Robson, and Neil Iyengar. We combine our expertise to provide comprehensive care to our patients at every step of their cancer journey.
