Forbes ranked physical therapists as having one of "The Ten Happiest Jobs," according to an article published in 2011. Physical therapists also report one of the highest job-satisfaction levels in the country according to a National Opinion Research Center survey, chronicled in an April 17, 2007 article of the Chicago Tribune in which more than three-quarters of physical therapists polled reporting to be "very satisfied" with their occupations. PTs were second only to clergy, and were the only health care professionals in the top 5.
