Investigation notes
Lanterman Regional Center is a private, non-profit organization that functions as a healthcare and social services provider, coordinating developmental disability services for residents of Los Angeles County. Given the nature of their operations, the organization maintains highly sensitive records, including comprehensive health history, diagnostic information, insurance details, and government-issued identification required for state-funded support programs. This data breach was officially reported to the California Attorney General in 2025, triggering formal notification requirements for those impacted. If you received a data breach notification letter, it indicates that your personal or protected health information was stored within their systems at the time of the incident.
