MEET DR. KASSONDRA S. GRZANKOWSKI
EXTRAORDINARY WOMEN’S CANCER CARE THROUGH CONVERSATION, EDUCATION, AND LOVE
“I cherish that I get to meet women at the beginning of their journey, help formulate a plan with them that can include surgery, chemotherapy, and radiation. I value the relationship that I get to continue while being their doctor through survivorship that helps ensure their greatest quality of life. ”
I appreciated early in my training that a longstanding relationship with my patients was just as important as performing complex surgery. I believe in being honest, teaching clearly, and showing up fully—whether that means guiding, supporting, or simply sitting with someone through a difficult moment. Cancer is hard, and my goal is to help patients navigate it with both expertise and humanity.
