    About Shaw, LA

    Shaw is a rural town in Louisiana that has never had any type of telephone service. With the leadership of Commissioner Foster Campbell of the Louisiana Public Service Commission and the efforts of Centennial Communications Corp., the local wireless telecommunications carrier, the residents of Shaw, Louisiana will now have access to modern and reliable telecommunications services. The availability of support from the federal Universal Service Fund ("USF") enabled the construction of two wireless towers in Shaw area, making possible the provision of telecommunications services to the community.
