The Trellis Center’s mission is to help participants increase independence in their lives through a variety of recreational and community engagement activities.

We strive to create environments where adults with developmental disabilities are understood, valued and given opportunities to grow individually as well as contribute to their community.

About The Trellis Center

The Trellis Center is a non-profit 501(c)(3) charitable organization that fosters a sense of purpose and belonging in teens and adults with developmental disabilities. The Trellis Center was created by a group of concerned parents who recognized the need for a creative, innovative, community-based program where adults with developmental disabilities are able to continue to learn, grow, have social relationships, and work toward independence. Staffed with highly experienced employees originally from across the country, the Trellis Center provides dynamic and integrated programming for individuals with any level of support need. Just as typical individuals, those with developmental disabilities need opportunities to continue to learn social, communication, leisure, recreation and employment skills. The Trellis Center will challenge and support each participant as they acquire these functional skills with the clear objective of continually improving their quality of life and developing increased independence so the individual can more adequately support themselves.

Program Hours

The Trellis Center is open Monday through Friday year-round excluding major holidays or inclement weather. Trellis follows the Ellensburg and Kittitas School Districts for closures and delays due to snow. You can check the school websites or listen to the local radio for these notices.

Transitional Program hours are from 9:00am – 11:00am. The program runs according to the school year from mid-September to mid-June.

On a typical day our programs will operate for 3 – 5 hours. This balance will fluctuate according to season.

The Trellis Center CSA

The Trellis Center operates a one-acre production vegetable and herb gardening program that is operated by adults who have autism and other disabilities. Founded in 2014 by a group of four young men with disabilities and their families.

Our produce and fresh cut flowers are available at local farmers markets, area restaurants and through our seasonal community supported agriculture program which provides weekly deliveries of our fresh, chemical-free produce to local customers in the Kittitas Valley. The farm is always busy with potting seedlings, mixing soil, watering, transplanting, harvesting, and marketing. In the process, our “Growers” learn not only hands-on skills in growing and preparing food, but also develop their executive function skills, problem-solving abilities, and self-advocacy tools, while gaining confidence as productive members of their community.

Trellis is also committed to cultivating a sustainable future. To us, that means practicing growing methods that are good for the earth and good for our customers while creating meaningful opportunities for individuals with disabilities.
