I am a board-certified nurse practitioner with special training in breast cancer survivorship issues. I am a graduate of Columbia University’s nurse practitioner program and joined Memorial Sloan Kettering in 2006. I focus on the long-term effects of cancer treatment and am dedicated to improving the quality of life of my patients.
