She did not. She completed >3.5 yrs of Neuro residency prior to being terminated. She then began working in "mental health" with a general practitioner license. She did not find a new residency, and her license is easily searchable/public information just like it is for every one of us.
Like <6 mos of training left.
Only 2 states allow you to practice without any residency as an "Associate/Assistant Physician". More information can be found
here, although I don't know much about the validity of that website. >30 allow you to obtain a full license with only 1 year of GME and completion of the national licensing exams (USMLE/COMLEX series). Virtually all allow a full license with completion of 3 yrs of GME and completion of the licensing exam series. More information about state requirements for medical licensure can be found
here.
What you can call yourself is highly variable and based on state medical boards and state-specific laws.
