USPB was a brand-new company when Mr. Linville was hired in late 1997 as Chief Operations Officer. Originally from a farm near Holcomb, Kansas, he developed many of the initial cattle delivery and analysis systems.

Prior to such date, Mr. Sellers will hold the title Chief Executive Officer - Elect. Mr. Sellers, originally from Ames, Iowa, completed his undergraduate work at Buena Vista University in Storm Lake, Iowa, and received an MBA from Iowa State University.
