Located in San Diego's Linda Vista neighborhood, the Community Research Foundation's IMPACT program provides comprehensive mobile behavioral health and supportive housing services for adults 18-59 who face serious mental illness and homelessness or housing instability. The program implements the Assertive Community Treatment (ACT) model, delivering a full spectrum of care including psychiatric services, medication management, substance use treatment, nursing care, psychosocial rehabilitation, housing assistance, benefits coordination, and support with everyday living activities. What sets IMPACT apart is its community-based approach, with over 75% of services delivered directly where clients live, ensuring accessibility and responsive care. The program makes housing an immediate priority, placing all clients in housing within their first week of enrollment. Funded by San Diego County's Behavioral Health Services, IMPACT serves Medi-Cal beneficiaries, Medi-Cal eligible individuals, Medicare recipients, and uninsured clients, maintaining a commitment that no one is turned away due to inability to pay.
