This is an NPI-based check only. NPISignal does not publish name-based exclusion matches on a provider profile. A shared or similar name is a lead that requires human review, not an identification, and this page is not the place to make one. Run a name-based screening below to see potential matches with the reasons for each.

Athletic trainers are allied health care professionals who work in consultation with or under the direction of physicians, and specialize in the prevention, assessment, treatment and rehabilitation of injuries and illnesses. Currently, the entry-level employment requirements are a bachelor's degree with a major in athletic training from an accredited university or college. A majority of athletic trainers hold advanced degrees. National board certification is generally required as a condition of state licensure and employment.
