Prior to the CHCC, she worked in the private sector, where she launched her own public affairs firm after running a practice in a Seattle-based PR firm. In both roles, she managed a number of campaigns for private, public and non-profit clients at the local, regional and state level. She created and implemented strategies to pass local and state legislation, improve community engagement, influence infrastructure projects, and secure funding for public agencies. She developed messaging, led media trainings and lobbied directly on behalf of clients.
