The California Network of Mental Health Clients (CNMHC) is a solely client-run organization whose membership consists of affiliates throughout California and over 1900 individuals. CNMHC has statewide and local expertise exemplified by the range of trainings and technical assistance, policy advocacy, leadership, recovery programming, networking and self-help and mutual support provided to clients, as well as to individuals and systems that come in contact with individuals with mental disabilities. 

CNMHC’s innovative contributions to the field of mental health have influenced both California and national mental health delivery systems. Most notably, the concept of "client culture" is now integrated into California's Cultural Competency Mental Health Plan. As well, two groundbreaking books on self-help and client-run programs are foundational to the field of mental health: Reaching Across: Mental Health Clients Helping Each Other and Reaching Across II: Maintaining Our Roots/The Challenge of Growth. Additionally, CNMHC led the Well-Being Project, the first client-developed research project in the nation, often referenced in mental health literature and practice and identified by the Surgeon General as groundbreaking.

As the formally recognized statewide advocacy voice for California's mental health clients, CNMHC brings to the WWT TAC expertise in developing and giving trainings and presentations, as well as technical support for clients and client groups, counties, contract agencies, other mental health organizations, disability organizations and other community partners to help create and support the success of persons with mental illness and co-occurring disabilities in the mental health workforce.
