I couldn't find anything naming her THE army surgeon general, just deputy SG. Dr. Kiley is still listed as being the surgeon general even on the army website and I found many quotes from him in the media from very recently.
I don't agree with a CRNA in a position that should be reserved for a physician however, she does have quite an impressive resume.
