I completed my undergraduate degree at West Virginia University and my Medical Degree at Duke University.  After internship and residency in Internal Medicine at Massachusetts General Hospital and Harvard University, I pursued specialty fellowships in Infectious Diseases and Clinical Pharmacology at the University of California, San Francisco.  Before coming to Kaiser Permanente, I spent 11 years as a faculty member at UCSF, seeing patients at San Francisco General Hospital.  I am committed to the health and care of all people living with HIV, hepatitis and other infections, with a special interest in gay men’s health.
