Helping house cleaner get insurance

Our house cleaner comes 1x a week, and she recently told me she stopped paying for her health insurance because it was too expensive. When we hired her, she said she was an independent contractor and handled her own tax and insurance things. I'm concerned about her, and I don't want her to be uninsured. I don't know the other people she works for, so I don't have a way to do something collectively. Obviously we can increase her pay/week to help her out. Just wondering if there are other organizations that help with this. In SF, when we lived there 8 years ago, I knew about La Colectiva, but I'm not sure if there's something similar in the East Bay. 
 

thanks!
