What Oparc does
Mission
Our mission is to support, employ, and transform the lives of individuals with disabilities. We ensure that people with intellectual and developmental disabilities (idd) have access to training, employment, and social opportunities, fostering a world where they are valued community members. Oparc has been at the forefront of providing comprehensive services and advocating for the rights and inclusion of individuals with idd since 1950.
As stated on its FY2025 Form 990.
Programs
Business services provides employment with competitive rates to individuals who are vocationally disabled and, therefore, are not yet able to meet the business requirements of the competitive labor market. In an industrial work setting, job skills and behavior training are provided to help prepare the participant for competitive employment or progression to other vocational programs. This program includes a supported employment program, which places people with disabilities into competitive employment within the community. A job coach provides training and continuing support for the participant while in the program. Business services also includes the Oparc explore program. Oparc explore provides the opportunity for individuals who want to explore community options, explore transitioning from a work activity program or who are currently employed but want additional activities such as: volunteering, building job placement skills, technology, community engagement, exploration, and adult living skills.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $13M to $17M (+26%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 85% · 2018 85% · 2019 83% · 2020 88% · 2021 92% · 2022 87% · 2023 2% · 2024 4% · 2025 4%. Grants only. Government contracts and fees sit inside program revenue.
88% of OPARC’s revenue is contributions — more donation-reliant than the typical peer (21% for the typical peer).

Who funds it, year by year
2017 → 2023: the base held at 9 funders, grant income rose $184k → $2.1M.
4 of 21 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 8% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of OPARC’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
OPARC leans on a few funders — its largest provides 66% of grant income and the top three 78%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
Largest funder’s share by year: 2017 37% · 2018 60% · 2019 39% · 2020 47% · 2021 71% · 2022 74% · 2023 90% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
50% of OPARC's funders are still giving 3 years after their first grant; 76% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
90% of OPARC's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $295k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
OPARC runs a healthier operating margin than half of the 2,297 human services nonprofits its size.
