As a credentialing specialists I work for healthcare organizations and ensure that physicians and healthcare facilities are in compliance with relevant regulations. I also keep records related to insurance contracts and staff credentials.

Because much of my work is done on computers, I must know how to use a variety of programs, including word processing and spreadsheet programs.
