MJB Freight Systems, Inc. formed in 1982 with three trucks as a sub-haul operation for a large California freight carrier. In 1985, MJB left the sub-haul business to provide direct service within Southern California. Immediately MJB saw growth potential with a niche LTL service. Focused on providing excellent customer service and timely efficient delivery, MJB is positioned to be your carrier of choice in Southern California.
