On July 26, 1990, President George H. W. Bush signed the Americans with Disabilities Act (ADA), a landmark piece of civil rights legislation making it possible for Americans with disabilities to participate more fully in society.  Twenty-five years later our world is more inclusive, but there is still more work to be done.  Opening Doors is a PhotoVoice exhibit that shows some of the obstacles USC students impacted by physical, mental, and psychological disabilities face.  The photos depict physical obstacles, social barriers and academic difficulties.
