The story is that DH has been pretty insanely busy at UPMC...and also UPMC compensation system is very corporate and productivity based. He has made a LOT of money as a rad onc. A lot. he was done.
He took an early retirement, and left UPMC in a lurch. Left pretty quickly, not on good terms.
this adds salt to the wound from what I understand, have heard, that he left to start his own business. But make no mistake - this business is classic 'rich guy' stuff - the guy has tons of cash and took well advantage of the UPMC comepensation/retirement set-up. All those RVUs added up. He's only 50 and bored, so this 'lark' (I mean how can this possibly be successful' will prob keep him entertained.
