Professional Statement
I enjoy internal medicine because it allows me to care for a broad range of patients. Given the complexity of medical care today with many new medicines as well as cutting-edge diagnostic technologies, patients need an advocate to help make sense of the complex information. I enjoy being the quarterback who explains medical jargon to patients while keeping an attentive ear to the more subtle aspects of their illness. I enjoy taking the time to help families understand the dynamics of their loved one's illness and offering frank and meaningful advice.
