KUHF-FM (NPR) Freq. 88.7 (Internet / Radio) 01/02/06http://www.kuhf.org/site/News2?JServSessionIdr005=1i0z21lpp1.app1b&page=NewsArticle&id=14927&news_iv_ctrl=1521 Stephanie Lahr sits in one of the simplest exam rooms you'll ever see, inside an old, non-descript two story building a few blocks off of Broadway in one of the island's toughest neighborhoods. She's a fourth-year medical student at the University of Texas Medical Branch and one of three clinic co-directors at St. Vincent's. Lahr and dozens of other UTMB students show up twice a week, on Thursday evenings and Saturday mornings, to provide free medical care to people who've run out of options.
