Steve Cox

Steve got started with IMMG on field trips, became a gift shop volunteer, and joined the Board in 2012. He also serves as field trip coordinator. More a biologist than a geologist, he still likes to understand Idaho geology on a landscape scale. Now retired, he worked in Boise for engineering companies MWH Americas and HDR doing wildlife analysis for environmental impact studies. Prior to that, he was a physician for 30 years, specializing in geriatrics.
