FoIB Chris Parks has a (relatively) new web tool, Find Your Doc. It's fast, easy, and free.
Have you forgotten your doc's phone number? Been traveling and need the name of a local cardiologist? Go to FYD, type in a name, or city, or a specialty (or any combination thereof), and voila! (French for "violin!"), up pops name, address and phone number.
Very cool, and very useful.
