Hi All -- Thanks for all of your input; it's been very insightful.
One of my biggest deterrents to applying to a PhD program is the 'Publish or Perish' mentality that exists within the field; the honest reality is that funding is tough to come by, post-PhD. While I'd like to be in academia, teaching or otherwise, tenured positions are also rare.
That said, I'm almost a year out of my MPH program and will most likely apply to a DrPH program in a few years -- it would probably make the most sense for me in regards to practicality and leadership. I'd have 2-3 years of management experience then -- do you think programs would seriously consider me, despite not being traditionally 'mid-career' (10 years in, etc)?
