Care Philosophy

"My experience working with grief expert and author Elisabeth Kübler Ross led me toward the field of oncology. Her compassionate care for cancer patients inspired me, and she helped me to understand the relationship between life and death. As an oncology physician who wants to be useful beyond just my technical skills, it's important to work through these types of issues for myself. Having empathy for what my patients are going through, and expressing that to them, is a vital part of their treatment."– Dr. Timothy A. O'Connor
