About the Autism Center of Nebraska

ACN is a certified developmental disabilities service provider under contract with the State of Nebraska Health & Human Services, Division of Developmental Disabilities. Nearly 150 individuals receive services from ACN, ranging in age from five to 65. Although ACN specializes in autism, we serve persons with a variety of developmental disabilities. Individualized services and supports are designed to lead to a higher level of independence for each individual receiving services, addressing the individual’s desires for his/her future. ACN provides a variety of residential, vocational, pre-vocational and educational services. At ACN, we believe that every person, regardless of disability, is valuable, and deserves to be considered valued members of their home community.
