The Arc Westchester

What The Arc Westchester does

The Arc Westchester is a 501(c)(3) nonprofit human-services organization founded in 1949 and headquartered in Hawthorne, New York. It is the largest agency in Westchester County serving children, teens, and adults with autism and other developmental disabilities, providing a full lifespan continuum of programs that includes Early Childhood Services, Wellness Center (psychotherapy, psychiatric, nutrition, and therapy services), Career and Employment Services, the Project SEARCH Autism Enhancement internship program, Community Habilitation, Recreation and Respite, Residential Services, Day Services, Crisis and Family Outreach with a 24-hour hotline, Guardianship and Supported Decision Making, and Transition to Adulthood programming. The organization delivers services across more than 60 community locations throughout Westchester County to nearly 2,000 individuals and families and employs over 700 staff, including 525 Direct Support Professionals.

The organization operates a service-delivery business model with no proprietary technology platform or AI/ML capability; service quality is governed by Council on Quality and Leadership (CQL) accreditation. Revenue is generated primarily through New York State OPWDD contracts and Medicaid waiver reimbursements, supplemented by charitable donations and signature fundraising events managed by its wholly-owned fundraising arm, The Arc Westchester Foundation. The Arc Westchester is a chapter of The Arc New York, which sits within the national Arc US network, and partners with NewYork-Presbyterian Westchester Behavioral Health, The Center for Autism and the Developing Brain (CADB), NEXT for AUTISM, Drexel University, The Y.A.L.E. Schools, AHRC New York City, and the Westchester Children's Museum to deliver specialized programs. Go-to-market is community-led: individuals and families access services through OPWDD referrals, healthcare provider connections, family outreach, and advocacy networks rather than commercial sales channels.

Operationally, the organization is currently led by CEO Tibisay (Tibi) Guzmán, who succeeded long-tenured executive director Richard P. Swierat in 2018, with Barry Clark serving as Executive Director of the Arc Westchester Foundation. Recent strategic activity has centered on expanding the inclusive-employment vertical, most notably through a three-year Taft Foundation grant awarded in April 2026 to launch the Partnership for Inclusive Internships (PII) Program with Westchester County Government and AHRC New York City.
