Do you refer to someone with a DBA as doctor?

A person with a DBA (Doctorate in Business Administration) should not be addressed as "Doctor" unless they have also earned a PhD (Doctor of Philosophy) in a related field. The DBA is a professional degree, not an academic degree, and does not confer the title of "Doctor". However, some individuals with a DBA may choose to use the title of "Dr." as a courtesy, especially in business or professional settings. It is important to distinguish between an academic doctorate (PhD) and a professional doctorate (DBA) when using the title of "Doctor".
