Sorry, I'm confused, does your husband have an MPH or an MD or both?
I'd be interested to know why someone who runs a health department doesn't think the entry level degree for his position is necessary, with or without an MD. I might be going out on a limb here, but I would think having a strong foundation in epi/biostats (gained from an MPH) would be ESSENTIAL to overseeing a health department. I can say that the epi/biostat training in med school is an absolute joke compared to what was taught during my MPH.
It would make sense that the accounting/managerial skills acquired during an MBA degree would apply to running a county health department given the job title and wide ranging budget cuts over the past decade (or more).
Still not convinced by all the posters saying an MPH is worthless as a stand alone or dual degree (MD/MPH). Obviously, if you aren't interested in public health, you are going to think an MPH is worthless TO YOUR CAREER, just as any other degree would be if you aren't interested in getting it. Still waiting for an MD/MPH to post his/her opinion on the matter.
