By far one of the most understanding and educated doctors in the area. Not only is Dr.Rahner well-versed in common and rare conditions, he listens to his patients and provides the best care he can; either by himself or through another specialist. It's hard to find a doctor who is willing to listen to you, explores different possibilities, and is willing to refer you to somebody else who knows your conditions better (aka, he isn't setting out to take on the role of every other specialist there is) if it means you'll get the care you need. I've seen him over 9 years, and have always felt listened to.
