Knoxville Hospital and Clinics will host the Mercy College Endless Possibilities Road Tour Wednesday afternoon, from 1 to 6 in the lobby at the hospital. Public Relations Director Katrina Nelson says it’s a good opportunity for high school students, or possibly someone who is thinking about going back to college, for a career in the healthcare field. She says Mercy College admissions counselors, faculty and marketing professionals, as well as several KHC staff members will be on hand as well to talk about their choice, and the job they do.
