A little bit of English isn't enough to get by at the doctor's office. Sitting side-by-side with immigrants at medical appointments, Baltimore County Department of Health interpreter Martha Lujardo tries to bridge the gap between the doctor and those with limited proficiency in English.

But there aren't enough of them to go around in a county with a rising immigrant population.
