Betsy is a communications officer at the David and Lucile Packard Foundation. Her expertise is in bilingual environmental communications, political and advocacy campaigns, branding, and media relations with a racial justice lens. She was born in Blue Island, Illinois, home to a now-shuttered Clark Oil refinery, and raised in the Southwest suburbs of Chicago. She’s lived on both coasts – and north and south in between – embracing the communities where work has taken her. She now resides in San Jose, California with her family. In her early reporting career, Betsy wrote for the U.S. Forest Service, Voice of San Diego, and the Rockford Register Star. While she thrived while reporting in English and Spanish on education, health, conservation, and hyper-local community news, Betsy found her passion in the environmental movement. As a mother, working on climate and ocean conservation provides her with the opportunity to do her part to make a difference for her son and generations to come. Prior to joining the Foundation’s communications team, she served as a Spanish-language media spokesperson for two national environmental organizations and one congressional campaign; her work spanned from both coasts to the Southwest, working with the communities there and in the states in between to grow their political power and hold polluters and public officials accountable. Some of the highlights of these efforts for her include her time at Earthjustice, as well as the League of Conservation Voters, with communications work to protect the Arctic from oil drilling, garnering stronger protections for farmworkers exposed to pesticides, training grassroots leaders to testify before the Environmental Protection Agency to safeguard the Clean Power Plan, working with families across the states to promote solutions to nix diesel pollution, and serving on the steering committee of the national People’s Climate March in 2017.
