Please don't forget to look into the positions/post docs with the Feds because not only do that have special pay for Clinicians, but you will likely also get loan repayment too. And no, you don't have to live in Metro DC to work for the Feds, although a significant number of positions are located here. Good luck!
The community college suggestion is a good one. You do not need a teaching certificate to teach at a CC. Our local CC is ALWAYS looking for science teachers. As SAHMdoc said, she won't make a lot of money, but having the loans forgiven after 10 years would be a very good thing. Good luck to both of you. I hope she feels better soon.
