My sister is not in anyway AP, so that is not a consideration, but they do not have good insurance, so the ability to pay out of pocket is important.
This not the Rockford area, I apologize. My son who has autism was diagnosed my Dr. Nishant Shah out of Luthern General Hospital in Park Ridge (near Chicago). He's a pediatric neurologist that specializes in ASD. I hope she's able to find someone closer, but I know good doctors with that specialization are few and far between.
