Casildo was born in the Central Valley. His journey with GRID Alternatives started in May 2021 as an IBT 200 Trainee. After graduating from the program, he started working as a residential/commercial solar installer in the solar industry. An opportunity to be part of the GRID Alternatives SolarCorps Fellowship Program arose, which led him to discover and develop new skills. After his fellowship term, Casildo was hired on as a Workforce Training Programs Coordinator. This allowed him to connect with the community even further, through active community engagement and working alongside with other partner organizations. As a result of his venture with GRID Alternatives, he now takes on the role of Workforce Administrative Manager at the very Training Center, where it all started for him. Casildo believes in the value of an opportunity and the potential within each individual to create their futures. He says, "At one point, someone believed in me and provided me with the space and resources to grow. It is a privilege to pay it forward and an honor to work alongside people who are invested in the life changing work that takes place at the Central Valley Training Center."
