County physicians. These staff physicians sought to establish an agency that could obtain additional funds to support and augment patient care, education, and research at the John Wesley facility. When the hospital was demolished in 1979, the agency continued its efforts to assist LA County patients, but the name was no longer relevant and was subsequently changed to JWCH Institute Inc.
