Mission Statement

Treeline Pass is committed to empowering adults with autism and developmental disabilities to cultivate lives rooted in purpose, joy, and growth in an inclusive community environment.

Organization History

Treeline Pass was started by three parents of children with developmental disabilities who saw a need for therapeutic day programming for adults in the Denver area. The organization was incorporated in the state of Colorado on April 24, 2018 and received formal IRS 501(c)(3) designation on May 31, 2018. Treeline Pass became a Program Approved Service Agency under the Health First Colorado (Colorado's Medicaid Program) Provider Network on January 25, 2021. We offer day habilitation, prevocational training, supported employment, and behavioral services for adults with autism and developmental disabilities. Our staff is committed to a culture of high expectations and limitless growth.


"As the parents of someone with Fragile X Syndrome, we are charged to give his life purpose. However, when he aged out of school at 21, we fell off a cliff. The variety of adult day programs we tried were unsuccessful and he ended up at home more often than he was able to attend. Treeline Pass is different because they offer therapeutic programming with highly trained staff. We're thrilled to once again have a partner in providing our son a life of purpose, filled with opportunities to grow and learn."
