To celebrate Developmental Disabilities Awareness Month, Trinity Services welcomed the public to an open house to learn more about the organization.

From 6:30-8 p.m. Tuesday, March 13, attendees visited Trinity’s Corporate Center at 301 Veterans Parkway in New Lenox to learn about Trinity’s residential options; community day, behavioral health and employment services; transition programs; and information about guardianship, the Prioritization for Urgency of Need for Services (PUNS) List, respite care and more.

Trinity’s mission is to help people with developmental disabilities so that they may flourish and live full and abundant lives. What it means to flourish is different for everyone, but it typically involves goals and dreams that people without disabilities have, like getting a job, pursuing a hobby, learning a specific skill, becoming more independent, or having closer relationships. To obtain these goals, it is essential for people with disabilities to be included in their communities, alongside people without disabilities.

Developmental disabilities may impact a person’s cognitive, behavioral or physical abilities. Examples of developmental disabilities are autism spectrum disorders, cerebral palsy, fragile X syndrome, Down syndrome and fetal alcohol spectrum disorders.
