Appointments for New Patients


As a board-certified genetic counselor, I help individuals understand their chance of having a hereditary cancer, options for genetic testing, and how testing results could impact their personal and relatives’ health care. I feel privileged to be part of patients’ treatment journeys, educate them about the ever-evolving field of hereditary cancer genetics, and discuss research opportunities at MSK. Before joining the MSK team, I had years of cancer genetic counseling experience focusing on hereditary breast and ovarian cancer.
