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.

Physician Assistants & Advanced Practice Nursing Providers
A physician assistant is a person who has successfully completed an accredited education program for physician assistant, is licensed by the state and is practicing within the scope of that license. Physician assistants are formally trained to perform many of the routine, time-consuming tasks a physician can do. In some states, they may prescribe medications. They take medical histories, perform physical exams, order lab tests and x-rays, and give inoculations. Most states require that they work under the supervision of a physician.
