1. USD Sanford School of Medicine — ASD Diagnostic Clinic (Regional)
The Sanford School of Medicine's ASD Diagnostic Clinic, based at the Health Science Center in Sioux Falls, holds clinics on the first and third Monday and Tuesday of each month for people who may have autism spectrum disorder. It is the closest autism-specific diagnostic clinic we found for Aberdeen-area families, roughly 200 miles away, so a trip to Sioux Falls would be needed.
