I knew Cmdre Kavanagh when she was CO 1 Fd Amb and, as an operator, she will be of great value to Health Svcs over the next couple of years. I think Col Hilliary Jaeger would have been a good choice as well.
I didn't notice it on this thread but are they combining the roles of DGHS and Surgeon General or keeping them separate?
If you note the article in your link was written by the Medical Post reporter whereas the Director Senior Appointments page is an actual DND biography. A/WSE to a civilian reporter or a civilian would make little sense.
When I was A/WSE I didn't run around with an A/ on my rank badge either.
