Mark Riskedahl, Executive Director
Mark grew up in a little house on the prairie in rural North Dakota. He received a B.A. from the University of Minnesota and his J.D. from Lewis and Clark Law School.  Before attending law school, Mark worked in the social services, primarily with people dealing with autism.  During law school, Mark worked as the NEDC Law Clerk, a Project Coordinator, and Student Director.  Following graduation, Mark helped institutionalize NEDC’s capacity to protect the environment and natural resources of the Pacific Northwest by becoming the organization’s first full-time Executive Director.
