The Executive Board serves as the elected officers of the county Party.  These individuals work tirelessly to make sure that the local GOP is governed effectively and that the efforts of our grassroots precinct committeemen are optimized to ensure sweeping Republican victories at all levels of elected office.

We are blessed to have a group of professionals with such a diverse set of skill specialties.  Members of the Executive Board are elected by the precinct committeemen for two year terms
