Founder, Earthshine Foundation
A beach volleyball and soccer player from Southern California, Andrew Castellano graduated from the University of California in Irvine with a degree in electrical engineering and spent the next 17 years as a computer chip designer. He led teams at the semiconductor company Broadcom in designing the industry’s first all-digital Fast Ethernet transceiver chips and the world’s first Gigabit Ethernet transceiver for copper wiring. After helping the company grow from a tiny startup into the world’s largest communications chip company, Andy left Broadcom to focus his efforts on philanthropy and the environment. He is the founder and president of the Earthshine Foundation, a private foundation created to fund environmental and other worthwhile causes.
A fortuitous visit to Sun Valley in 2011 with his wife, Kim, was all it took to make Andy trade in the sand for the snow and to turn his attention to issues impacting his new home. Being naturally attracted to “charged” subjects, he joined the Ketchum Energy Advisory Committee and subsequently became a founding board member of the Sun Valley Institute for Resilience. His primary focus is on clean energy, where his background in electrical engineering intersects his passion for protecting our environment.
