Shawn Marshall sees California as setting the bar for the rest of the country. As the Co-founder and Director of the Local Energy Aggregation Network, Marshall supports the expansion of clean energy community choice aggregation (CCA) nationwide. Her organization serves as a hub for resources and expertise. In 2007, Marshall served on the task force that ultimately became the Marin Energy Authority, which serves a customer base of over 100,000 accounts in Marin and the City of Richmond with a range of 50%-100% renewable energy.

In addition to her work in the CCA field, Marshall served two terms on the Mill Valley City Council, as Mayor in 2008 and Vice Mayor in 2013.
