Historical Background

The role of California Surgeon General was created in 2019 by Governor Gavin Newsom with the understanding that some of the most pernicious, but least addressed health challenges are the upstream factors that eventually become chronic and acute conditions that are far more difficult and expensive to treat. The position’s responsibilities include advising the Governor, serving as a leading spokesperson on matters of public health, and driving solutions to our most pressing public health challenges.

Our mission is to advance the health and well-being of all Californians.
