From 2000 to 2006, he worked as the technical director and senior producer for Michigan Radio's regional environmental news service known as the Great Lakes Radio Consortium.

From 2006 to 2010, as the unit's co-manager and senior producer, Mark helped transition the GLRC into an award-winning national news service known as The Environment Report.

He has won several state and national awards for his work, including a 2011 national Edward R. Murrow award for best audio news documentary on the future of coal in the United States.

Mark is a graduate of the University of Michigan ('00 MS in Environmental Policy and Planning & '91 BA in Political Science) and has been a "public radio junkie" since 1992. Much of Mark's storytelling philosophy was influenced through his close work with veteran CBC "réalisateur" David Candow.
