You may want to try doing a Google or other search -- it has been discussed on this site before that, because the allnursingschools site basically charges schools
to advertise there, it's not
a comprehensive list of all available programs. Many schools just choose not to pay to be listed.
Since you have previous degrees and know what direction you want to go in nursing, you may want to skip a generic, "basic" nursing program and go directly into a "direct-entry" MSN program, if you can find one with the gero NP specialty -- these programs are designed for people who already have (at least) a BA/BS in something else, and combine basic nursing education and an MSN program in one program. You graduate (in 2 or 3 years, depending on the program) with RN licensure plus the specialty advanced education, in one fell swoop.
Best wishes for your journey!
