I am looking for a list of PA schools in the Greater Los Angeles and
Orange County areas. The qualified answer will contain complete
current address and main contact information.

Hello expensiveanswers:

Thanks for the question. 

The most authoritative place to find accredited schools for PAs is:

American Academy of Physician Assistants (AAPA)
URL: http://www.aapa.org/

According to their General Information page:

Information About PAs and the PA Profession 
URL: http://www.aapa.org/geninfo1.html
Quote: "PAs are trained in intensive education programs accredited by
the Accreditation Review Commission on Education for the Physician
Assistant (ARC-PA).
Because of the close working relationship the PAs have with
physicians, PAs are educated in the medical model designed to
complement physician training. Upon graduation, physician assistants
take a national certification examination developed by the National
Commission on Certification of PAs in conjunction with the National
Board of Medical Examiners. To maintain their national certification,
PAs must log 100 hours of continuing medical education every two years
and sit for a recertification every six years. Graduation from an
accredited physician assistant program and passage of the national
certifying exam are required for state licensure."

This site has "a state-by-state listing of all accredited PA programs."
