A group of motivated parents began building our history of services for adults with disabilities in 1966.

< back


Back when our local area was called the Pomona Valley, services for adults with intellectual or developmental disabilities (I/DD) were extremely limited.  The regulatory landscape was very different, and there were few options for care and services, outside of state institutions.  This limited availability of care options created anxiety and challenges for these individuals and their families.

Motivated to ensure a full and productive life for their disabled adult children, a small group of determined parents created Pomona Valley Workshop (PVW) in 1966.  This new organization served 15 individuals and provided programs out of their own homes in Southern California.

Since then, our rich history of services for adults with disabilities has transformed and grown over the past 50 years.  Today, this non-profit organization serves about 400 individuals each year in both facility and community-based programing in Montclair, California.


In 2016, PVW was at a crossroads. How do we maintain the operational foundation of those first parents, while leading the way through some of the most significant changes to our industry since the 1960’s.

We took a hard look at our mission, our programs and services. Most importantly, we considered what would be best for the people we serve.  As a result, we created new opportunities and programs for our community.

In 2017 we officially changed our name to Anthesis.  This change reflects our strong commitment to providing the resources and opportunities for individuals to blossom in the greater community. Additionally, we are developing a new Transition Employment Program to better prepare individuals who are interested in Competitive Integrated Employment (CIE).

Although founded as Pomona Valley Workshop, our legacy of services for adults with disabilities continues as Anthesis.

In 1969, the proposal of the landmark “Lanterman Mental Retardation Services Act” (AB 225) recognized the need for legal rights and responsibilities for persons with developmental disabilities. The basis of this act became law eight years later in 1977 (Lanterman Development Disibilities Act” (AB 846).

Since the beginning, our operational philosophy has been consistent with the intent of the Lanterman Act – to create opportunities for adults with disabilities.  Our program goals were designed using the framework developed for Community Rehabilitation Provider (CRP) organizations.  This philosophy focused on providing a safe, nurturing, and active facility-based programs.  This “workshop” concept was very much in alignment with the regulatory and advocacy landscape of the time.

The regulatory and advocacy environment has since evolved. The philosophy of this internally-focused work environment has waned as the positive benefits of more integrative programs have emerged. Through recently passed regulations, such as the Home and Community Based Services (HCBS), as well as the Workforce Innovation and Opportunity Act (WIOA), critical program funding has increasingly been directed away from internally-focused programs and toward more integrative programs and services. By 2022, compliance with these new integration-focused standards for all programs serving the I/DD population will be mandatory.
