Trinity Services, Inc., founded in 1950, is a nonprofit, nonsectarian organization that provides the highest quality person-directed services and supports to people with developmental disabilities and mental illness so that they may flourish and live full and abundant lives.

Trinity serves more than 3,500 adults and children who have intellectual/developmental disabilities or mental health needs. Trinity’s mission to help people flourish is at the heart of all it offers, including residential services, numerous community day services, employment services, a school, therapeutic horseback riding, respite services, a recreation center, a range of therapeutic services, and more.
