About.

We are a family owned and operated company located in beautiful Colorado, and have been serving the interstate trucking community since 1991.  Evilsizor is a family name from our original pioneer, Rex Evilsizor.

Established in 1990

Rex Evilsizor, a former ICC Special Agent, began this company as Rex Evilsizor & Associates.  In 2004 he handed the company over to his daughter, Penni Royston.  Since then she has created a friendly online experience knowing just how busy and mobile everyone is these days. Of course you may always give us a call and chat!

Our Goal

We specialize in servicing the small trucking companies and brokerage firms.  It is our mission to help companies better understand the rules and regulations in simpler terms.
In our 28 years we have serviced over 100,000 companies.
