Look on your state's website for job listings at the health department. I am planning on getting my MPH and I am excited. That's usually what public health employers are looking for because it teaches public health specifically. If you are not happy, then maybe public health isn't what you want and maybe teaching is?
There have been postings for public health jobs that I have seen for public health nurses that do OB/GYN teaching and deal with new mothers. PHNs that work in health depts usually have 8-5, Monday-Friday schedule. So, you may be able to do an evening clinical or class teaching. It would depend on where you teach and everything. I know that nursing clinical instructors are in demand and sometimes, class room instructors. The thing is, you have to have a degree above what you are teaching. The only exception is doctorate's.
RNs (ADN/BSN) can teach LPNs
Master's prepared nurses can teach BSN/ADN and LPNs
Doctorate prepared nurses can teach Doctorate's, Master's, BSN/ADN, LPNs
I hope that helps a little.
