The Job Accommodation Network (JAN) is a disability accommodation consulting service. It a wonderful free service funded by the federal government that most people don't even know exists.
If you call JAN's toll free number you will reach a staff person who will ask you about your disability and the challenge you are trying to overcome. You can ask about a particular job or a task that is an important part of that job. Consultants at the center specialize in strategies to overcome different limitations. Ask to speak to a specialist in the disability area of interest to you (vision, hearing, speech, paralysis, specific learning disabilities, allergies, carpal tunnel syndrome, mental retardation, head injury, cerebral palsy etc.)
The consultant will discuss approaches with you. They may send you information on technology that they think will solve your problem or they may ask other experts to help. Sometimes they will need to call you back so they can research your problem. They may advise you to contact a technical specialist in your local area and give you referrals.
Generally speaking, you will find JAN staff knowledgeable and genuinely interested in helping. (If you get that occasional person who doesn't seem to know their stuff, call back and ask to speak to another consultant).
You can call JAN toll free by dialing 1-800-526-7234. Before you do, however, you may want to spend just a couple of minutes checking out JAN's Website.
