What Chaddock Attachment and Trauma Services does
Mission
Chaddock's mission is to help children and families thrive by providing trauma-informed services that promote healing, stability, and lifelong well-being.

As stated on its FY2025 Form 990.
Programs
Chaddock's Developmental Trauma and Attachment Program (DTAP(R)) continued to deliver life-changing, trauma-informed residential treatment for children and adolescents who have experienced severe abuse, neglect, and complex trauma. Grounded in attachment science and neuroscience, DTAP focuses on building healthy relationships, emotional regulation, and long-term family stability. During the year, the program served 209 children and family members from 15 states, demonstrating Chaddock's national reach and the growing demand for specialized trauma treatment. Through highly individualized therapeutic care, education, and family engagement, youth showed measurable growth in emotional, behavioral, and relational functioning, with many progressing toward permanency and successful reintegration into family or community settings. The program also continued to receive national recognition as an evidence-based, relationship-focused model that strengthens children, families, and the systems that serve them.

Through comprehensive recruitment, training, and ongoing support of foster families, the program ensures children receive trauma-informed care while working toward safe and lasting permanency. During the year, Chaddock's efforts helped 91 children achieve permanency through reunification, adoption, or guardianship, while the organization also licensed and added 37 new foster homes to expand placement capacity and meet growing community needs. By strengthening foster families and providing intensive case management and support services, the program continues to improve outcomes and long-term stability for children and families.
$5,312,330 spent$4,647,451 earned by the program19% of program spendingChaddock's therapeutic school provided individualized, trauma-informed education for students whose complex behavioral and emotional needs could not be met in traditional classroom settings. The program integrates academic instruction with therapeutic supports to help students regain stability, build life skills, and reengage in learning. During the year, the school served 151 students from 20 area school districts, offering a structured and supportive environment designed to promote academic and personal growth. As a result of these intensive supports, students achieved an 83% graduation rate, including many youth who were not previously on track to graduate before enrolling. The program continues to play a critical role in helping students overcome barriers, achieve educational success, and transition to brighter futures.

These services include family support and preservation programs, adoption and post-adoption supports, independent living and transition services for older youth, and community-based mental health and consultation services for children and caregivers. Through training, in-home and community interventions, and ongoing family engagement, these programs help families build resilience, maintain safe and stable homes, and reduce the need for more intensive levels of care while supporting positive outcomes for children across the region.

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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $19M to $20M (+5%).
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 49% · 2018 47% · 2019 46% · 2020 49% · 2021 54% · 2022 59% · 2023 57% · 2024 56% · 2025 53%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 7 funders, grant income rose $57k → $157k.
3 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 27% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $11M from one payer (the payer shares this organization's board, largest Chaddock Childrens Foundation). These are real filings, and they are not money CHADDOCK ATTACHMENT AND TRAUMA SERVICES raised.
From the IRS filings of CHADDOCK ATTACHMENT AND TRAUMA SERVICES’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
CHADDOCK ATTACHMENT AND TRAUMA SERVICES has a broad base — no single funder exceeds 25% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
53% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund CHADDOCK ATTACHMENT AND TRAUMA SERVICES.
Largest funder’s share by year: 2017 83% · 2018 57% · 2019 66% · 2020 28% · 2021 32% · 2022 28% · 2023 33% — diversifying over time.
“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
60% of CHADDOCK ATTACHMENT AND TRAUMA SERVICES's funders are still giving 3 years after their first grant; 77% 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
66% of CHADDOCK ATTACHMENT AND TRAUMA SERVICES's grant income comes from Illinois funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $316k 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.
