Very casual and pre-ordained. I started my career at the NAM while I worked on my PhD. My boss became a partner at Patton Boggs at a time when tax reform was very hot. PB had a dynamic partner who had been at Treasury who's dream was to recreate the multidisciplinary team he had had at Treasury at PB. It was understood that when I finished my PhD I would go to PB. I was working on the Hill as I finished my dissertation and very involved in the tax reform act of 1986. Having graduated, as soon as the Act passed I moved to PB. There were some pro forma discussions with the executive committee but it was pretty much preordained--and the result was a job at PB that lasted 27 years.
