Kimberly C. Head ShotKimberly Christensen, Communications and Social Media Coordinator

Kimberly Christensen is the Communications and Social Media Coordinator for CoolMom, delivering educational and thought-provoking information about climate change to our members. She began volunteering with CoolMom in 2008 as part of the Greenwood CoolMom group. Since that time, she has project-managed several activist campaigns, including the temporary installation of a pinwheel wind farm at Greenlake and the development of CoolMom's No-Idle Toolkit.
Kimberly became an environmental activist while in college, sparked by a professor who introduced her to the problems caused by factory farming, Big Ag and soil depletion. Prior to becoming a mother herself, she worked as a midwife. Wanting a bright future for all of the babies who have touched her life - including her own two children - she decided to focus her energy on the climate crisis and work to find solutions to this threat. Kimberly lives in Seattle, WA, with her husband Dave and their two children, Soren and Aniela.


Our History

CoolMom was founded in 2007 by two long-time friends, Kirsten Bergstrom and Kristy Royce.  With atmospheric scientists in both of their families, they were well acquainted with the climate issue. As mothers, they saw an urgent need to unite mothers to address the climate crisis and to advocate for future generations. The organization traces it's beginnings to a party, when Royce invited friends to view the film, An Inconvenient Truth. The conversation that ensued among the mothers present led to the launch of CoolMom.
