Care Philosophy
My goal is to provide excellent patient care. Doing so requires: 1) understanding each patient as a whole person – their goals, dreams and the challenges they face – and 2) forming a collaborative relationship so that we can work together to navigate diagnosis and treatment as it impacts their life.
