RotaCare Facts

RotaCare Bay Area was founded in 1989 by a local Rotarian with the support of his Rotary Club.

RotaCare provides care to the growing population of working and unemployed residents who are unable to pay for primary healthcare.

RotaCare Bay Area is heavily supported through grants, donations, and the hard work of our volunteers.

The UCLA Center for Health Policy Research estimates that even with the Affordable Care Act, 11% of Californians will remain uninsured.

All RotaCare healthcare services provided at the clinic are free to the patient including medical exams, diagnostic testing, lab testing, and most pharmaceuticals.

RotaCare saves taxpayer dollars by providing patients accessible medical care in our community clinics rather than expensive emergency room care.

Two unique things about RotaCare are:
1) we provide free medical care

2) the organization is volunter
