There's no ways to get student loans completely forgiven that I'm aware of. The best you can really do to minimize debt is to get scholarships, and then keep them and pick up more scholarships by getting good grades in pod school.
The military residency in NC (I think there is one in WA now also?) will give you some student loan help in addition to salary, but you are on the loop to work with the service for some years after finishing the residency. It's fairly complicated and you'd have to look into it for full details...
There are rumors floating around about loan forgivness for working in rural areas or Native American reservations, but I think those programs are just for MD and maybe DOs. I haven't seen any such offers for DPMs...?
