Chelsey Fitzgerald


Chelsey Little comes to the California Adolescent Health Collaborative with over five years of contract and budget management experience. She is passionate about systems creation and implementation. She enjoys facilitating and overseeing complicated procedures/processes and looks forward to supporting CAHC in this capacity. Chelsey grew up in Austin, Texas as one of five children in a low income household with one primary breadwinner. The first in her family to go to college, she graduated from Stanford University with Distinction and a BA in English Literature. Having benefited from the generosity and diligent attention of caring adults during her own adolescence, Chelsey is well aware of the village it can take to bring resources, opportunities, and helpful information to otherwise underserved or unsupported youth. For this reason, she is excited to be able to work behind the scenes to support CAHC projects and goals.
