I personally know three Excelsior College RN grads. One of them is self-employed as part owner of an ambulance service. The other two have never had any problems finding work as nurses. Their Excelsior degrees have served them well.
When I worked as a recruiter I worked on a few nurse projects. The employers I worked with, including some very prestigious hospitals, couldn't care less about the source of your degree. But I think the article captures my feelings on the topic of "What do employers think about my degree?" regardless of your field in one simple quote: "I think most employers are looking at the candidate as a total package. And really, they're less concerned with where did the degree come from than just what are their overall skills and their ability to perform."
