The Microsoft Regional Director (RD) program is a community of independent developers, architects, trainers, and other professionals who form a vital link between Microsoft and the developer community. These technical experts provide insight and informed perspectives about Microsoft software development tools and technologies. Regional Directors are not Microsoft employees, nor are they monetarily-compensated by Microsoft. They are recognized by Microsoft for their technical expertise. Many Regional Directors are also Microsoft MVPs.
As of Spring 2008, there were approximately 50 Regional Directors in the United States and 120 Regional Directors worldwide. Microsoft selects Regional Directors in geographic areas based on customer and developer density. Although "regional" appears in their title, Regional Directors are not bound by any set geographic boundaries. In fact, most travel to evangelize their technologies. You will find Regional Directors speaking at conferences such as Tech Ed, PDC, Visual Studio Live!, Dev Connections, Mix, PASS, and various user groups and Code Camps throughout the world.
