Justin Stewart became the owner of GBE Mandrel in late July 2024, after years of learning from founder Steve Stabler. Justin since 2006 would visit the shop to absorb knowledge from Steve while pursuing his Automotive Engineering degree, graduating in 2009. He worked on commercial fishing vessels, automotive electrical, and heavy-duty equipment. As an ASE Master Technician and Custom Vehicle Upfitter, Justin gained valuable experience before returning to Steve’s shop. With Steve’s focus on mandrel bending and exhaust components, Justin took ownership, continuing the legacy.
