Oak-Leyden Developmental Services

UPDATED: January 3, 2019

Oak-Leyden Developmental Services was originally formed in 1956 as the Oak Community School by the concerned parents of children with developmental and intellectual disabilities who sought the very best social, health, and economic outcomes for their family members. It quickly evolved into an agency offering community integrated housing and day programming for adults living in Chicago's western suburbs who require sustained attention for their developmental and physical needs as they grow older. In 1975, Oak-Leyden extended its programming to include a Children's Services division that delivers Early Intervention therapies to young children with developmental disabilities and delays. Oak-Leyden now provides more than 500 adults and children in western Cook County with comprehensive, person-centered programs and services that meet their residential, vocational, clinical, and developmental needs.

Mission and Goals:
The mission of Oak-Leyden is to help children and adults with developmental disabilities meet life’s challenges and reach their highest potential.

All of Oak-Leyden’s programs and services for people with intellectual and developmental disabilities are informed by our seven core values:
• Recognize the dignity of each individual.
• Support personal choices whenever possible and safe.
• Promote inclusion of each individual served within the larger community.
• Facilitate and encourage family involvement and participation.
• Strive to discover new and innovative programs to enhance the lives of people with disabilities.
• Provide individually-designed programs that empower our clients.
• Use resources in a manner that provides the maximum benefit for individuals.

Core Programs/Activities:
Oak-Leyden maintains a unique approach to developmental services by ensuring that all programming remains person-centered and focused on the autonomy and individuality of each client we serve. This approach directly supports our participants’ need for services that promote their quality of life and their dignity as people. We consistently deliver services that further the growth and expand the independence of people with developmental disabilities in three program areas:

Children’s Services: Children from birth to five receive therapies through Oak-Leyden that improve outcomes related to their developmental disabilities and delays. We offer developmental, occupational, speech-language, and occupational therapies following a family-centered model that takes advantage of everyday learning opportunities. We also provide developmental screenings to ensure children are connected to the precise therapies they need, as well as integrated group education programming that helps them become better included in their communities.

Residential Services: Oak-Leyden’s community integrated living arrangements (CILAs) provide adults with developmental disabilities with comfortable, family-like homes in communities throughout the Greater Chicago Area. We offer 24-hour support and care that promotes the personal independence and physical well-being of our residents. Oak-Leyden hosts a Multidisciplinary Clinic as part of our residential program to ensure participants receive appropriate and timely attention to their health and wellness needs.

Lifelong Learning: Oak-Leyden operates adult day programs in Oak Park and Elmwood Park. Program offerings include developmental training that furthers adult independence, vocational assistance, and a Supported Employment Program that has secured positions for clients at businesses including Aramark, Jewel-Osco and Costco.

Key Accomplishments:
Oak-Leyden programming has an established record of delivering strong outcomes for its clients. In 2017, Oak-Leyden was awarded a three-year, gold level accreditation for its day and residential programs from CARF International. Ninety percent (90%) of individuals in Lifelong Learning Center programs met or exceeded their goals for daily living as documented in their Individual Service Plans. The organization maintained a 100% record of having no founded abuse and neglect claims and has remained in 100% compliance with its required licensing and accreditations. Oak-Leyden’s Children’s Services also received a 100% score from the Illinois Department of Human Services Early Childhood Monitoring.
