Depends on how your GP refers you. Mine just referred me to the clinic, not a specific Dr, so when I called the clinic they picked a Dr for me. If you have an idea about what your issues may be, you could spend some time on google to find out who might be good. Only problem is, there's not a lot of info out there because of the websites worrying about being sued. Otherwise, just discuss with your GP and try whichever FS they recommend. My GP said they're all the same, which isn't true, but there are some GPs out there who know who's best for treating various issues.
