Finding the right physician who is the right fit can require many "interviews." Don't be afraid to "just say no" if the doctor you see isn't a good fit. Above all, don't give up. The right doctor is out there. Like the fairy-tale princess, you may have to kiss a lot of frogs before you find your prince/princess.
Personal referrals are often the best way to find a good doctor. If you belong to a support group, ask people in it. Ask if you can use their name when you call for an appointment.
