For many Adults with ADHD Work and Career issues can be a huge challenge. Some Adults with ADHD have the resources to work with an ADHD Coach or a Career Counselor. However there are many adults with ADHD who either do not have the resources or aren't able to use the resources they do have.

Since ADHD is covered under the Americans with Disabilities Act, Vocational Rehabilitation services Adults with ADHD. For more information about your own local office just Google: Vocational Rehabilitation and the name of your state.
