Philosophy of Care

“Every day, I strive to remember that patients entrust us with what is most precious—their health—and also to appreciate how the healthcare experience can be an unexpected, life-changing, and concerning one. I therefore aspire to treat every individual as a whole person and to promote a supportive environment where every patient is heard, respected, understood, and is offered the safest and highest quality care.”
