I don’t get what you are trying to get at here. He is a Doctor. Same way DPTs are doctors or Podiatrist are doctors. They are all physicians at the end of the day. He went fours years of undergrad and took four more years in a Chiro school so in the end he is a doctor. He has a doctorate degree that is recognized in all 50 states and by insurance companies.
Although I didn’t want to shyt on buddy, Nicole is actually right. If a Chiropractor and a Physical Therapist were in a hospital setting, they cannot be addressed as “Doctor” because it causes confusion with the actual MDs especially when you are around patients.
Just because you have an actual doctorate degree, does not give you license to use the title “Doctor”. It’s not even appropriate in academic settings. Individuals that have PhDs should be referred to as Professor instead of “Doctor” in the academic setting and nothing at all outside of academics.
You even have nurses that have PhDs in Nursing. They cannot be referred to as “Doctor” in a medical setting when actual MDs are around. It’s confusing to patients and those with MDs take precedence.
