San Ramon or Pleasanton for Special Ed/Indian Family?

We are an Indian family with a 9 year old who is 2E with ADHD and ASD (high functioning). We are looking to potentially move to San Ramon or Pleasanton. Two specific questions:

1/ How do these districts compare in terms of supporting special ed needs within the school but also through placements in private/NPS schools?

2/We are looking for a closer knit Indian community thats open to welcoming new people coming into the community with young kids.

thanks for perspectives!
