Welcome to OSU Metro Extension

Welcome to the Portland metropolitan area Oregon State University Extension Service!  OSU Extension is charged with providing research based information as well as informal educational opportunities for all Oregonians. In the Portland metropolitan region Extension leads Oregon State University's engagement and outreach mission with innovative urban programming in partnership with leading community organizations and agencies as well as more traditional offerings through faculty at our Clackamas and Washington County offices. 

The resources and information located on these pages reflect the needs and interests of people in this region; local food and farms, nutrition for all, sustainable living, urban gardening, rural urban connections, and youth programs. Our program partners include Portland State University, the Portland Public Schools, Portland Parks and Recreation, Metropolitan Council, Multnomah Public Health, Multnomah Commission on Children Families and Communities, the Oregon Food bank, and East and West Multnomah Soil and Water Conservation Districts. 

If you have questions or suggestions for Extension programs in the metro area, please contact Patrick Proden, Metro Regional Administrator, via email or phone, 503-821-1150.
