About DJI Gin Repair
Family Built. Field Tested. Built to Last.
DJI Gin Repair is a family-built cotton gin service company based in Lubbock, Texas. We specialize in equipment rebuilds, gin saw stacking/training, brush and rib replacement, preseason inspections, maintenance and gin-season service support. Our work comes from decades of hands-on experience — learning the craft the right way, by doing it. We take pride in working steady, working honest, and standing behind every cotton gin we service.
Where We Come From
Mario & Rosa Cortez
The roots of DJI Gin Repair began in the late 1970s, when our father, Mario Cortez, started his work in the cotton gin industry at Owens Co-op Gin. Through dedication, skill, and steady leadership, he rose to Superintendent, providing for our family and laying the foundation for who we are.
In 1996, he established D & J Gin Repair, and later, in 2007, we — Daniel, Jimmy, and Isaac — continued that vision together as DJI Gin Repair. We learned this trade the same way Mario did — by working. Alongside him and our mother, Rosa, we spent years stacking and training saws, rebuilding gin equipment, making brush sticks, and installing carbide ribs. Those hands-on years formed the standard we still operate by today.
Rosa’s strength and support held our family together, and her influence remains in how we treat our crew and our customers: with respect, honesty, and care. Their values are still the backbone of DJI — faith, work ethic, and commitment to the people we serve.
Their values are our foundation.
