MPH as a career change. Worth it?

[Rcoll90]

Is an MPH and a career in Public Health advisable for a career change? I already have a Masters (Operations Management) and no medical/science background but I am very interested in Public Health/Policy especially as it pertains to homeless and veteran populations.

As a mid-career change, can I expect to earn decent money soon after graduating? I will be retired from the military by the time I commit to a program (in 5 or 6 years) so I won't require a huge salary but the potential to make $60K+ not too long after school would be nice. Is this realistic? I would not targer elite schools, but decent programs like Drexel, Temple, and others an the Philly/NJ area. And finally, is an execuive MPH applicable to somebody in my situation?

Thanks.
