About The Rolling Wrench

The Rolling Wrench was founded in 2025 by Vartkes “Vic” Ghukasyan, a lifelong trucker with a deep understanding of what it means to break down miles from home. After years on the road, Vic decided it was time to shift gears—away from life behind the wheel and toward helping other drivers stay on theirs.

With decades of hands-on trucking experience and countless hours spent fixing his own rig, he turned his passion for wrenching into a full-time mobile repair business.

Viejo

Broke down just outside Frazier Park—cooling system started acting up and had me dead in the water with a full load. Called around, and most places either didn’t answer or told me it’d be hours. Then I got ahold of Rolling Wrench.
