APCTC was established in 1977 as a directly-operated program of Los Angeles County Department of Mental Health. APCTC was the very first mental health center in Los Angeles County specifically developed to meet the unique needs of rapidly increasing numbers of Asian Pacific immigrants and refugees who were in need of a wide range of mental health services. Through intensive program development efforts in response to ever-growing service needs, APCTC has since expanded to its current operation with multiple funding sources. In 1990, APCTC made a major transition through privatization to become a county-contract agency, and has since been under the auspices of Special Service for Groups, Inc (SSG).
The APCTC staff consists of over 100 highly trained mental health professionals, paraprofessionals, and support staff. The professional staff consists of fully credentialed psychiatrists, psychologists, social workers, marriage family therapists, nurses, case managers, rehabilitation counselors. Most of these professionals are themselves of Hispanic or Asian Pacific heritage and bilingual, representing language capabilities in Spanish or Asian languages including Cambodian, Chinese (Chiu Chow, Cantonese, Mandarin & Taiwanese), Japanese, Korean, Laotian, Filipino (Tagalog), Thai and Vietnamese.
