José oversees projects and teams on the fabrication floor, making sure information flows clearly across every build and that material stock and finished product both meet Lime Media's standard.

Michael oversees multiple projects and teams on the shop floor, making sure information is communicated and documented clearly, materials are stocked and ready, and every finished build meets Lime Media's standard. With 10 years as a mechanic, police upfitter, and shop manager in Missouri — including being named EVT of the Year in 2017 — plus two years running his own cabinet shop, he brings a rare range of hands-on trades experience to the team. Nearly 3 years into his time at Lime, he still gets the biggest kick out of building custom one-off pieces and watching people enjoy the final result.
