"When a community has a need, Extension’s role is to listen, learn and ask good questions. We then harness the power of the university to help meet community needs and help residents co-create the things they want. Ultimately, we’re connectors and conveners and supporters." - James Pritchett, Vice President of the Office of Engagement and Extension.

In addition to overseeing CSU Extension’s statewide network, OEE includes the Colorado Water Center. Starting in July, the division will expand to include the Colorado State Forest Service and CSU Spur, the university’s public-facing campus in north Denver.
