I believe I have found the PERFECT program for any high school child with ADHD, dyslexia, dysgraphia or dyscalculia.
It is The Leelanau School near Traverse City. I got the chance to visit the school and was blown away by how good the teachers are, the experiential-based, integrated curriculum, the strength-based learning strategies component and the residential life program.
The place is beautiful, right on the banks of the Crystal River and Lake Michigan.
