NP or MPH?

Hope that's okay, I've cross-posted this.

I graduate with my RN soon, and I have a previous BA in another field.

I have worked as an LPN for almost 10 years in an office, then M/B, and now on an acute medical floor. Prior to being an LPN I worked for a couple of years as an aide and unit secretary on this same floor. I've been thinking about where I view myself in 10 years, and I see myself in some sort of low-managerial position--public health clinic or school clinic, for example, or DON at a larger doctor's office, that sort of thing. I have no desire to take on the world, but don't want to be a floor nurse FOREVER, if no other reason that I don't think it will be physically possible!

I just always assumed I would go into a NP program; but recently a friend applied at a Masters of Public Heath program. She was not accepted, in part because she did not have much health care experience. Her application process has gotten me thinking, though. It seems like a good track for where I would like to see myself. But in some ways, it limits me a bit, too, if only in that NPs have a lot more lateral job possibilities.

Anyone here explored the MPH option?

Any thoughts?

Thanks, J
