There are a few lenders still offering private student loan consolidations, but if you only have one loan, that may not work for you. Another option would be to look into another type of credit, like taking out a personal or home equity loan, but the rate and terms of the loan would depend on your credit, income, and other debt.
Honestly, with a relatively small loan like that, I would focus more on getting it paid off ASAP, then trying to refinance, which, while it might save you a few % in interest, could cost you in fees and time spent.
