Sierra Martinez

I grew up in Martinez, California, a place that engendered my interest in energy and the environment, as it embodies both: bordered by ample natural beauty: golden rolling hills, the Carquinez Strait, and Briones Regional Park, but also the location of prominent, large, oil refineries. I've carried this with me throughout my learning and career.

I enjoy skiing, hiking, independent music, reading, and just hanging out with family and friends.
