If they are already a nurse-practitioner, and took further coursework to get the DNP, the D standing for doctor, I have no problem with calling them doctor, because that’s what they are. That’s at least three years of post grad, and probably four, anyway.
I might point out that many physicians brought back / insist on / prefer being called physician instead of doctor because of the issue you have raised. And it was when pharm schools started graduating doctors of pharmacy that MD’s started having the “doctor AND physician” attitude.
