There were 183 patients at Rock Hill's Piedmont Medical Center on Tuesday. Nurse Betty saw them all. Not most. All. Now in her 55th year at PMC, Betty Jenkins, who has been at the hospital longer than most employees there have been alive, has a new role - patient ambassador. Just a fancy title for what Nurse Betty has always done during decades in obstetrics, where the babies are born and miracles happen - bring a smile to everyone she sees. Only now, it's her full-time job.
