How do I find out which pediatricians DO NOT take medi-cal?

I've had very bad experiences with doctor's that take medi-cal, and I would like to avoid that at all costs. I called a couple doctor's and asked if they take medi-cal, but how will I know if they take providers like healthy family and insurances through medi-cal? Medi-cal doctors seem to never really pay much attention at all to my kids because they have to see so many patients, so I would like to avoid that at all costs. We're paying quite a lot for our kids' insurance and i'd like to see our money's worth since they do both qualify for medi-cal/healthy families.
