L.A. Care Health Plan

I would like to know how much emphasis L.A. Care Health Plan places on primary care. Are most of their patients already in advanced stages of illness/disease by the time they come in? Finding out how they promote preventive care would also be interesting to learn about. I would also like to know how long wait times are and whether seeing a specialist is difficult. Do patients have to jump through hoops to see who they really want or is it fairly easy?
