Glen Colton

Treasurer, Board of Directors

Glen and his wife have lived in Fort Collins, Colorado since 1979. They have one daughter. Glen has been active in the community for many years, serving on numerous boards and commissions involved with community planning, the environment, open spaces, natural resources, sustainability, and economic health. He has been especially active in population and growth issues at the local, state, and national level. For many years, he wrote a bi-monthly business column for the Fort Collins Coloradoan, focusing on providing an alternative view to the pro-growth bias dominant in the media. Glen worked at Hewlett Packard and Agilent Technologies in Finance and retired in 2001. He graduated from Wartburg College in Iowa in 1978 with a degree in Accounting and Economics. While growing up in Iowa he developed a passion for the outdoors hiking, fishing, camping, canoeing, and hunting. He also was a three-sport athlete in high school and college, playing football, wrestling, and track. While Glen believes in taking individual action to help achieve sustainability, and protect the environment and wildlife, he believes it is equally important to stabilize population and move our economy to a “steady state” economy not dependent on economic and population growth. When he’s not working on sustainability issues, Glen enjoys fly fishing, biking, hiking, downhill and cross country skiing, gardening, and just being in the outdoors.
