Hopkins pulmonologist and critical care specialist Panagis Galiatsatos draws on his Greektown roots to connect with the "undoctored." Galiatsatos, a proud Greek American known as Dr. G, understands the kinds of patients predisposed to getting sick in Baltimore. They are lower-income residents, or immigrants who don't speak English, or renters in apartment buildings with poor air circulation. They are people without insurance, people without doctors they trust. He knows them because they are his old neighbors, fellow parishioners, friends. And he knows that if he can't reach them, it will only widen the chasm between the health system and the neighborhoods that surround it. / Johns Hopkins Magazine
