Your T. is probably not that expert on the rules governing this. There is such a thing as a "benefits advisor," but I'm not sure how you find one. I knew someone who very effectively combined collecting SSDI and working as much as allowed. She had a "benefits advisor." I think she got one through the state Vocational Rehab office. This person has very specialized understanding of how to avoid pitfalls that can threaten your benefit from SSDI.

Go to the blue pages of your phone book, or go online, and find the address and phone number of your Division of Vocational Rehab. Your state has such an agency, and it has offices in every good-size city in your state. Go register with them.
