Patient Care Philosophy

I’m passionate about providing compassionate, patient-centered care to women with breast cancer with a special focus on young women. I pride myself in being an educator and an advocate for my patients. I believe that at the center of excellent cancer care, is the understanding that patients are more than a diagnosis but rather a whole person. I believe that the therapies and treatments of the future are essential for my patients to have access to today. This is why I’m proud to be a leader in advancing cancer care through clinical research.
