If an older adult faces an immediate, life-threatening emergency, call 911 instantly. For ongoing or suspected care failures in a Santa Rosa nursing home, you should contact the Sonoma County Long-Term Care Ombudsman at (707) 526-4108 for localized advocacy. To trigger an official state investigation that can result in regulatory citations and fines, file a formal complaint online with the California Department of Public Health (CDPH) via their Cal Health Find portal.
