Julie Propp landed her first-ever job about 18 months ago — at age 55.
A part-time retail helper at a Kwik Trip convenience store in Marshalltown, Iowa, Propp cleans and ensures coffee cups and other items are well-stocked. She previously loaded boxes in workshops run by agencies that help disabled people but never had a traditional job because of a developmental disability.
