Will Carington, works for Noodle
According to Kumon's website, Kumon centers do indeed work with children with learning differences/disabilities. To find out more about the specific capabilities of the Kumon Center of Orlando - Goldenrod, I'd recommend contacting the center directly either via email or at 407-673-1130.
You can also use Noodle to easily browse tutors who specialize in ADD/ADHD in your area. Hope this helps!
