Gene Maitlen
In Memory of Gene Maitlen

 In 1972, Gene Maitlen and Bob Vaughn got into the dredge manufacturing business in a Quonset hut near their Case Equipment dealership in Oklahoma City. Bob, Gene, and Randy Maitlen, Gene’s son, decided to become serious about building quality dredges and created Vaughn-Maitlen Industries (VMI), Inc. The VMI, Inc. plant was located in several locations during the next four years until 1976, when the production facilities finally settled in Bethany, Oklahoma. Bigger and better dredges were soon added to the VMI line and a network of distributors was set up. As one of the most recognized dredge manufacturers, VMI, Inc. began to sell VMI dredges worldwide and an international salesman was added to their staff.

By 1989 VMI had outgrown its current plant capacity and a decision was made to build a new production facility in Cushing, Oklahoma. The new production facility was specifically built for manufacturing dredges. In 1997 Bob Vaughn’s stock was purchased by Gene Maitlen and his two sons, Tony and Randy, making VMI exclusively owned by the Maitlen name.  In 2007 VMI's facility was expanded to include additional manufacturing and parts storage space for increased capacity.

At the end of 2019 VMI introduced a new logo to better reflect the company name and image going forward.

In 2020 VMI's testing and training capabilities were enhanced to improve product innovation and better serve the needs of customers.  Additional parts storage capacity was also increased to expand the availability of in stock items.
