The Davis Dyslexia program is not based on evidence-based therapy, and specifically goes counter to the well-established research base in reading development of 30+ years depth (e.g., he explicitly avoids phonological processing, and espouses a number of long-debunked ideas about dyslexia as a visual processing deficit, with relationship to balance and coordination).

Your money would be better spent on $17k of effective Lindamood Bell or Orton-Gillingham therapy, than $1000 of bogus therapy.
