DrPH?

I'm a practicing Psych/Mental Health nurse practitioner, and I am also currently in the process of getting a post-masters in Perinatal Nursing and I'm planning on pursuing doctorate studies sometime in the near future and I'm interested in hearing from any other RN or APRN who has a DrPH, or is considering getting a DrPH.

The majority of my work, both psychiatric and perinatal, has been community based, usually in-home or in-school, with a fairly sizable health education component as well and I'm very interested in program/curriculum development, access to care issues and general policy concerns. However, I'd also really enjoy getting involved in academics at some point, university level teaching, program development, that sort of thing, and a doctorate is basically de riguer in academic circles, I'm just not sure which one is a good fit for me!

I'm not really interested too heavily in straight research, although I am interested in program analysis/efficacy research, but not really true nursing science, you know? So, I don't think a PhD is a good fit for that one purpose alone, although I'd love to hear other opinions about that. So the I thought about the DNP, which is more clinically geared than the PhD of course, but after speaking with some of my previous professors (two of whom have DrPH's!) they mentioned looking into the DrPH over the DNP, as my interests, per them, lay in more "public health-y" type fields and not pure nursing fields. What do you all think? Does that make sense? Would DrPH be a poor use of time and money and energy? Does anyone out there on this site have a DrPH already? I'm feeling very overwhelmed by my options and I'm really not sure where to go at this point! Thanks!
