We are here to beat COVID-19 together

Our Mission
Who we Are
We are a team of doctors, epidemiologists, public health experts, students, and technology leaders who are working together to defeat COVID-19 in California, with an emphasis on underserved and vulnerable populations.
Knowing where the infection is hiding and where people are vaccinated helps the public health department and hospitals to direct resources to where they are needed most, potentially saving lives and getting our state back to normal. We chose diverse households to represent the entire county. We wanted people from all walks of life—all genders, races, ethnicities, ages, etc.--and we wanted people located in different places throughout the county to create a balanced snapshot.
