Credit specialists and credit questions

[Andrew Syrios]

My father, despite never missing a payment in his life, has fairly mediocre credit due to, we think revolving debt. 2 Questions:

1) We think some of it may be because the credit bureaus view 2nd loans from banks (which he has a couple of) as revolving credit. Does anyone know if this is true?

2. Is there a good company that specializes in improving credit, specifically for businesses, that anyone knows of. Thank you in advance.
