Kaiser Permanente’s history dates back to 1933 in California when Kaiser and several other large construction contractors had formed an insurance consortium called Industrial Indemnity to meet worker compensation claims.
The company grew quickly by insuring large groups of construction workers doing work in the region.
During World War II expanded defense spending led to increased workers in the Richmond Shipyard. Henry Kaiser set up an insurance plan for these workers. This entity survived the shipyard project, and is the direct descendant of Kaiser Permanente.
Today Kaiser Permanente is an integrated managed care consortium made up of three distinct entities: the Kaiser Foundation Health Plan, Kaiser Foundation Hospitals, and the autonomous regional Permanente Medical Groups.
Kaiser is the largest managed-care organization in the United States with 8.9 million health care members, 167,300 employees, 14,600 physicians, 37 medical centers, and 611 medical offices.
