Mark Juedeman grew up on a ranch in Montana where he acquired a life-long commitment to the natural world and environmentalism. He retired from a 30+ year career as a geophysicist in 2010 so that he could devote his time to volunteer service. He and his family lived for many years in New Orleans where he was active in historic preservation, bicycle advocacy, education, the environmental non-profit The Green Project, and obtaining personal experience with renewable energy technologies such as small wind and PV. Mark obtained a Permaculture Design Certificate in 2009 after being displaced to Houston by Hurricane Katrina. He is a founding member of Transition Houston, a member of the executive committee of the Houston Food Policy Workgroup, serves on the board of Urban Harvest, teaches with the Permaculture Guild of Houston, and is a lecturer at the University of Houston. Mark became a certified US Transition LAUNCH instructor in 2012.
