Special Needs Pediatrician

Hi! I have a four year old with diagnosed Autism. We are unhappy with our current pediatrician (kids care pediatrics). They aren't patient with my son and expect him to do things as a "typical" child. Literally zero understanding of the needs of neurodivergent kids.

Has anyone had positive experiences with a pediatrician in Frederick County (i will travel) that is wonderful with all kids, even ones who are a bit "different"?

Thanks!
