My Story

From a young age, medicine has been the only career I ever aspired to. I have had the opportunity to work in institutions across the country. I have also been lucky to work with talented individuals in caring for patients who truly illustrate the strength of the human spirit. I started out at Cedars-Sinai in Los Angeles, where I was appointed Assistant Professor at UCLA. Following a move to New York, I worked at Albert Einstein College of Medicine, but I did not feel a general practice was fulfilling enough. It was then that I got what I consider a “winning the lottery position” at Memorial Sloan Kettering Cancer Center (MSKCC). I had an incredible mentor, the Chief of GYN Oncology, Dr. Bill Hoskins, whom I credit for giving me the opportunity to become the physician I am today and who helped me find my niche in cancer survivorship. I spent 17 years at MSKCC during which I built one of the earliest women’s cancer survivorship programs in the country. Throughout my tenure at MSKCC, I was surrounded by incredibly talented and dedicated physicians, nurses, trainees, and assistants.
