In 1972, the first Center for Independent Living was founded by disability activists, led by Ed Roberts, in Berkeley, California. These Centers were created to offer peer support and role modeling, and are run and controlled by persons with disabilities. According to the IL approach, the example of a peer, somebody who has been in a similar situation, can be more powerful than a non-disabled professional's interventions in analyzing one's situation, in assuming responsibility for one's life and in developing coping strategies.
