Bison Building Materials, LLC., based in Houston, Texas, began modestly in 1962 as Roy W. Bierschwale's small retail store an ... d lumber shed. Over the past four decades, Bison has grown into Texas' single largest independent supplier of lumber, full service millwork and other added value products.

Bison broadened its offerings with the acquisition of Custom Craft Millwork Company in 1973. Today, Bison operates fourteen divisions in Texas, Colorado, New Mexico and Florida providing construction packages ranging from form lumber to roof decking, as well as a wide range of commodity and custom doors, columns, cabinet doors, molding, plywood and stair parts, all delivered directly to our clients' jobsites.
