South Bay Guidance Center in Chula Vista operates as a Community Research Foundation program at 1196 Third Avenue, serving adults aged 18 and older with serious mental illness and co-occurring substance use disorders across southern San Diego County. Medi-Cal certified through San Diego County's Health and Human Services Agency Behavioral Health Services division, the center delivers integrated, strength-based, trauma-informed care — a recovery model that coordinates with physical rehabilitation providers including Manual Orthopedic Physical Therapy for patients whose psychiatric conditions manifest as chronic musculoskeletal pain. A bilingual and bicultural clinical team provides services in English and Spanish, addressing the behavioral health needs of the South Bay's large Latinx population through culturally competent psychiatric evaluations, medication management, and group counseling. Enhanced programming serves transitional-aged youth ages 18 through 24 and older adults 60 and above, with vocational rehabilitation, supported employment, and education services rounding out the recovery continuum alongside wellness referrals to mindfulness-based providers such as Chula Vista Yoga Center. Treatment modalities include cognitive behavioral therapy, motivational interviewing, relapse prevention planning, and integrated dual-diagnosis protocols that apply the ASAM Criteria dimensional assessment framework to determine appropriate levels of care for patients presenting with concurrent substance use and psychiatric disorders.
