Founded with great help from Post Carbon Institute in 2009 and governed by a Memorandum of Understanding with the international Transition Network, the mission of Transition US is to catalyze a network of communities working to cultivate a just, caring, resilient, and regenerative world through training, support, and collaboration. Our Board of Directors oversees the financial health and strategic development of the organization, while four part-time staff members run operations.

Gabriela Silva Hernandez

Network organizer

Gabi (they/she) is deeply rooted in community, self-love, and practicing holistic sustainability. Growing up in alternative economy structures, they realized how pivotal community is in addressing and meeting the needs of one another through non-extractive exchanges. They have three years of experience in working with unions, founded a local community pantry in Isla Vista, and facilitated healing spaces for LGBTQ and misogyny-affected people. Through their work, they have brought attention to issues of gender-based violence that exists internationally, held space for mutual exchange of support, and fought the greediness of large corporations and institutions. 
They believe that the first step in creating a more equitable and regenerative future is imagination, because “para soñar es vivir”(in order to live, one must dream first). Having collaborated with people from all walks of life in political, healing, and creative spaces, they realize how vital storytelling is in understanding one another as well as envisioning transformative change. 
They aim to create intentional space that uplifts stories and ideas as to what a liberated future will be. 
In doing this work, they ground themselves through meditative practices such as yoga, meditation, and nourishing their body with what Earth graciously offers. 
With a B.A in Black Studies from UCSB, they have devoted themselves to a life-long commitment in dismantling oppressive systems and institutions whilst incorporating healing and joy going forward.

Alex Zubia

Network organizer

Alex Zubia, who goes by “Xef” is a Chef by trade. Born and raised in Fresno, CA (yokuts Land). Alex attended The California Culinary Academy in San Francisco (Ramaytush Ohlone land) in 2007. His passion for cooking came with his passion for eating. From 2008-2015 he worked at Community Regional Medical Center’s Emergency Room as a Patient Liaison. During that time he witnessed people from his community dying from diet related issues. That realization led him to opening his food truck, which  focused on healthier, farm to fork versions of familiar foods. In 2015, Alex moved to Santa Barbara (Chumash Land) to further his skills as a chef. There, he discovered that so much of the beautiful produce he was cooking with came from Fresno. He wondered why he never saw all this produce available in Fresno. Alex moved back to his hometown in 2021 to fight for food justice as a Food Sovereignty Director at Fresno Barrios Unidos. Alex’s goal is to bring his community back to eating and cooking their indigenous foods which are so plentiful in the Central Valley.
