Don retired after forty-four years at Esri as Director of Consulting Services. This work took Don around the world helping to design GIS systems for clients like New Zealand Forest Products and the Hong Kong Lands Department. Living in Bishop since retirement has allowed Don to volunteer with non-profits as a way of giving back for his years of enjoyment exploring our public lands.  In addition to supporting Whitebark, Don is the board chair for the Eastern Sierra Interpretive Association (ESIA).  Don also co-founded the UCR Geographer’s Scholarship for Global Change Science and Sustainability that supports graduate students at the UC Riverside Edge Institute. In his spare time Don and his wife enjoy hiking, kayaking, flyfishing, cross country skiing, and anything that will allow them to enjoy the eastern Sierra and Death Valley.
