Well I kind of like ol Randal Paul...according to WIKI his not being board certified is more a matter of protest against the way the organization re-certifies doctors as opposed to he isn't a good doctor. It used to be lifetime once you passed the test and were certified but they changed how they did it and Paul thought it was a money grab.
(According to WIKI he passed the certification test on his first attempt). Paul is a graduate of Duke Medical School and has hospital privileges at two hospitals in his area.
