i have had two private docs and am currently at an accredited cf center. my experience with private docs has been way less than satisfactory. the last one didn't know squat about cf, and to make matters worse, he was unwilling to hear me out on anything. doing much of my own research was useless because he was the doc and i was the patient. he was the only pulmonologist available to me at the time, and when i could get seen at a center, i switched immediately.
the other time was right after i turned 18 and the pediatric cf specialist i saw would no longer see me. i went to a pulmonologist who was right upstairs, then went to a gastro guy down the hall. i guess the experience with them wasn't horrible per se, but my intussuseption got by both of them for five years, until an e.r. nurse tried calling my bluff on my abdominal pain, and i was scehduled for an immediate endoscopy.
in short, my experience has been much better at a center, but i'm sure it has a lot to do with the team. the team at uihc seems to have their spit together; i'm in and out under two hours (it takes longer to drive there!!) and conversations pick up practically where they left off three months prior.
after all that, my input boils down to what others have already stated. try talking to your team, or if you're just plain fed up and want to try a different route, be prepared to do lots of cf footwork on your own (not you don't already!!), and be sure to find pulmonologist that is willing to learn form you. after all, what good is doing your own research if the doc won't listen?
