Hi Maritta -
I'm skeptical of credit repair services in general. All they can really do is examine a client's credit reports for errors and, if found, ask the credit agency to correct them. People can do that themselves. A professional service might be more effective in getting an agency to correct an error if discovered, or in getting a creditor to withdraw an erroneous report, but there has to be such an error in the first place to get any benefit - and it has to be a serious enough error to have a significant effect on the client's credit score.
Credit counseling is a different matter - that helps people learn how to improve their credit and devise a plan for doing so. It can also help them explore options for finding loans for people with poor credit. There are a number of HUD-endorsed agencies that provide this service for free or at reduced cost for disabled or low-income persons.
