Hello, There is now a directory of PD clinical services at U.S. universities, university hospitals and research instituitions at http://www.pdindex.org (under topic "care givers, professional"). This may be of help to anyone who is looking for a movement orders specialist. For anyone unfamiliar with PD Index, I invite you to take a look at this web site that I've put together with the hope of making it a little easier to find information on the Internet about the various aspects of PD.
