Drive Clean Colorado, a Clean Cities Coalition
The Drive Clean Colorado, a Clean Cities Coalition works with vehicle fleets, fuel providers, community leaders, and other stakeholders to save energy and promote the use of domestic fuels and advanced vehicle technologies in transportation.
Bonnie Trowbridge brings a deep knowledge of the market—from consumer EVs to alternative fuels to heavy-duty manufacturers and fleets, and a comprehensive understanding of the vehicle incentives arena across the U.S.—to her role as Executive Director for Drive Clean Colorado, a Clean Cities Coalition . With over 25 years of experience in business development for nonprofits and corporations, Bonnie is focused on achieving breathable air for everyone by advancing the clean transportation industry. Her past experience includes nonprofit development and fundraising, grant writing and management, and events management. She also spent 11 years in public relations and marketing for Lightning Systems, manufacturer of electric powertrains for medium- and heavy-duty buses and trucks, where she was instrumental in growing that company from a start-up to a thriving manufacturer. Her experience includes program management for CALSTART, a non-profit organization working to commercialize clean and efficient transportation solutions, where she led events such as a California policy summit, industry leader workshops, and utility engagement programs; and work as a development director for nonprofits in Denver and Washington, D.C. Bonnie is the co-chair of the Colorado Women of EVs chapter and a volunteer EV coach for Drive Electric Colorado.
