I felt the same way until I started being more active in choosing quality doctors. Doctors are no different than any other profession - there are the ones at the bottom of their league that are just going through the motions and there are the superstars working for some of the best institutions in the world. The key I have found is to specifically look for doctors that are either actively involved in academic research pertaining to your ailment or are working at quality institutions that are engaging in research that is at least tangentially related to your issue.

Keep in mind they also have to do a stupid amount of paperwork these days for every patient and the place they work for may be overscheduling the crap out of them - generally (unfortunately) I always consider my first appointment to be sort of a wash due to this and assume I am not going to really get anywhere until the second time I see them.
