Looking for a PhD/DBA Program (have multiple graduate degrees)

[Merlin]

National accreditation is fine if you are pursuing it for business purposes and have no plans to become a researcher or tenured college professor at the university level. In the business world, regional vs national degree accreditation rarely a factor since most places don't even know what the differences are. So a DBA from an NA university is generally no big deal since it is a professional degree and not a research degree. You just want to make sure that your DBA program meets your personal and professional needs, which may include granting access to the right alumni network or whatnot.

If teaching is on your bucket list, then you may want to look at other options. You would normally need a regionally accredited Ph.D. to teach at the university level in the US. That said, some universities do allow tenure track professors with a DBA. In which case you'd likely need a regionally accredited DBA degree to qualify, and it will probably need to come from an AACSB business program as well.
