Who We Are
Built right. start to finish.
One Stop Services started with two guys, a truck, and a conviction that general contracting didn't have to be complicated. Twenty years later, we're licensed in 40 states and still running every project the same way — on time, on budget, no excuses.
The One Stop Story
One Stop Services was founded in Gilbert, Arizona by Ty Mangum — a veteran of large commercial GCs who was tired of watching projects get bloated by bureaucracy, miscommunication, and subcontractors who didn't show up. He believed a leaner, more accountable model could deliver better results for owners and developers.
What started as a one-man operation focused on tenant improvements in the Phoenix metro quickly expanded. By 2018, One Stop had completed its first multi-state QSR rollout — 14 locations across the Southwest in a single calendar year. That project became the template for how the company operates: tight coordination, self-performing where it matters, and a single point of contact from permit to punch list.
Today, One Stop Services operates across 40 states with a core team based in Phoenix and a trusted network of regional trade partners. We build commercial developments, QSR rollouts, custom homes, and industrial facilities — and we bring the same discipline to a 2,800 SF drive-through as we do to a 120,000 SF distribution center.
What We Stand For
Accountability
One point of contact. One team responsible. We don't pass the buck — we own the outcome from groundbreaking to final walkthrough.
Precision
Schedules are commitments, not suggestions. We plan obsessively so that surprises stay off the jobsite.
Craftsmanship
We self-perform where quality matters most and hold every subcontractor to the same standard we hold ourselves.
Transparency
Owners get clear reporting, honest timelines, and no hidden costs. If something changes, you hear it from us first.
