It's was clear to me, after numerous visits to several MSK NYC facilities, and MSK Basking Ridge, that they invest a lot of time and effort, organizationally, in training and continuous improvement programs, etc. They must have really good hiring practices as well, because I've never met anybody in their facilities that was less than wonderful to deal with.
Also, and this will sound like I'm joking, but I'm not, the MSK hospital in NYC seemed populated by an amazingly good looking staff. It was actually pretty weird; like being surrounded by models. Their other facilities, that I visited, were a much more normal distribution of attractiveness.
