Prior to elective office, Rapp served as a community relations representative with Beverly Health Care in Warren, Pennsylvania. She volunteered for the Parent Education Network in York, Pennsylvania. She also worked as a compliance monitor with the Pennsylvania Department of Education, where she helped examine special education programs and served as a consultant with the Parent Education Network.[3]
Rapp was "very much" opposed to legalizing medical cannabis in Pennsylvania, believing that it could open the door to full adult use cannabis legalization.[5][6]
