Susan Thornton, founder and Co-Chair of IPC
She is a native of the Upper Peninsula of Michigan.
She earned a Bachelor’s degree from Michigan State University and a Master’s degree in Journalism from UCLA, then worked as a member of the Los Angeles News Bureau at U.S. News & World Report. Following her move to Colorado, Susan was a consulting writer for numerous news magazines, and for eight years was an opinion columnist for The Denver Post.
Susan is a strong believer in preventing social and other problems; for 10 years she held a clinical faculty appointment in Preventive Medicine at UC Health Sciences Center, where she wrote/edited numerous books and training videos before running successfully for the Littleton City Council. She served 16 years on the Council, eight of those years as Mayor of Littleton, where she co-founded the Metro Mayors Caucus, sat on the Board of the Colorado Municipal League, and led communities across the U.S. caught up in Superfund litigation.
Susan was a founder of the Littleton Leadership Academy and today is the founder and chair of the South Metro Community Foundation. She is a consulting writer for the Special District Association of Colorado and other organizations.
She and her husband have extensive international travel to far-flung countries, such as Borneo, where they erected solar panels to provide electricity at a remote orangutan research station. They have a grown son who is married to an immigrant from Bulgaria, who Susan says has greatly enriched their lives, and one lovely granddaughter.
Susan enjoys time with her granddaughter, playing the Great Highland Bagpipes, taking tai chi and ballroom dancing lessons, visiting with friends, reading and community-organizing.
