Barbara Knoll, MD


Commitment to Patient-Centered Care

"I live by the motto, “To whom much is given, much will be required.” (Luke 12:48) I am a humanitarian, a compassionate physician who makes no distinction in the face of suffering on grounds of gender, religion, nationality or color. I grew up in an impoverished country, and because of that I have been drawn to help others less fortunate. Being trilingual (Spanish, German and English), I am often called upon to help interpret on behalf of patients and their families."
