Hi Tim,
You might want to check out the masters in gerontology offered at SF State. I trained as an Ombudsman for the city for a clinical EC, and several of the other Ombudsmai-(sp?? lol)-in-training were masters students in this program. They had GREAT things to say about it, seems like a cool program.

Good luck in your career change, btw! Cheers.
