Office of Public Health (OPH)

(916) 930-3981 + Extension

The Office of Public Health ensures that high quality health services are available for Indian people in California. We accomplish this goal by helping the tribal and urban Indian health programs meet nationally accepted standards of care for healthcare organizations. Our professional staff provides training and technical assistance in addition to performing basic federal functions such as contract monitoring and health program performance evaluations. Our mission is to: monitor health status; empower health care providers and consumers about new innovative practices; and join with other health care partners to improve access and delivery of care. We assure proper licensure credentialing is being used and national accreditation is being sought by Tribal, Urban and Buy-Indian health programs.
