We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2024

• 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.

• Chaddock's Foster Care program continued to provide safe, nurturing, and stable family environments for children who have experienced abuse, neglect, and family disruption. 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.

• Chaddock'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.

• In addition to its core residential treatment, foster care, and therapeutic school programs, Chaddock provides a continuum of community-based and family support services designed to strengthen families, prevent placement disruption, and improve long-term stability for children. 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.

As filed on the 2024 return.

Officers and directors · 2024

As listed in Part VII of the 2024 return, in the order the filer printed them. Each return names its own; this is not a roster the organization keeps with us.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.
