Trinity Diversified Inc., began as a sole proprietorship of the startup company Trinity Enterprises. The president and owner, John Foster, gaining much success from 1995 to 1999 made the decision to Incorporate. In 1999 the new company name was proudly introduced as Trinity Diversified Inc. The new name came with a commitment from those in management to the last employee. Trinity Diversified Inc. stands on the importance of a proper Christian attitude towards all individuals we come in contact with.


Currently Trinity Diversified Inc. is the largest highway striper manufacturer in the Southwest United States. We custom manufacture truck mounted, long-line, airless paint striper's up to 33,000 GVW, legend marking trucks (stencil trucks), self-propelled highway line striper's, centerline, side gun mounted, and the new addition of RPM's (button) application bodies.
