Dr. Robert Colvin has practiced medicine for 7 years, and is on the medical staff of the California Pacific Medical Center in San Francisco, California. He remembers wanting to be a physician since the age of 4, when his preschool took a tour of the local hospital. Something clicked when young Dr. Colvin was handed his very first surgical mask. In medical school, he spent a month in Nepal doing medical and clinical work. He also trekked to the base camp of Mt. Everest. This witty, optimistic Chicago native hopes to someday use his expertise to volunteer in third world medicine.
