Changes at the Museum of Glass?

We came across this listing last week and thought we had the beginnings of a story. The Executive Director of the Museum of Glass, Josi Callan, has her house up for sale. How curious. Then, the word got to us tonight that Ms. Callan is officially leaving the Museum. The rumor on the street is that it will be effective at the end of the year. Details anyone? Red ink everywhere. Nearly 100% turnover since opening. A city art museum (TAM) with a better private glass collection than the Glass Museum. Why leave now?
