She moved to Sonoma in 2001 while working for a local caterer as a wedding/event planner and knew right away that she never wanted to leave. After attending a new-member recruitment event for Impact in 2016, she quickly realized this was a group she needed to be involved with! The mission of collective giving and support for the nonprofit community is one that resonates deeply for her. As a dedicated volunteer and member of several local nonprofits, she takes pride in being a valuable and contributing member of her community.

Chelsie Runnings,  Assistant Communications

Shortly after the Valley Fire, Chelsie felt a need to put roots down in her community in Sonoma Valley, and joined Impact100 in 2016 as a member of the first cohort of the NextGen program. In her time spent between working and volunteering you can typically find her with her two dogs and her boyfriend and family, enjoying the ocean or in the kitchen trying some new recipes. 

Angela Ryan, Co-Communications

A Sonoma native, Angela returned to the valley in 2013 after earning a doctorate in history and spending nearly a decade as a college professor.
