Weight Loss Surgery Friendly PCP in Los Angeles

My daughter has decided she wants to have weight loss surgery. She currently has to choose her Medi-Cal health plan and the choices are L.A. Care and Health Net. Anyone have WLS with either of these and can you recommend a WLS PCP who will not give a lot of hassle? She has been deciding for years if she wanted to do this and is finally ready, it would be a shame to have a PCP who would be discouraging.
