About Us
Built by People Who Started on the Ground
GMB Powerline Services is a woman- and lineman-owned and operated utility contractor that partners with utilities, cooperatives, and municipalities to build, maintain, and restore the grid, safely and to standard.

What Sets Us Apart
Woman- and Lineman-Owned and Operated
Most utility contractors look the same on paper. GMB does not. Ownership that spans both the business and the field means decisions are made by people who understand the work and the standard it demands. Clients get a partner who communicates clearly and follows through. Crews get leadership that respects the job.

How We Work
Consistent Leadership, Crews That Scale

GMB pairs a core of experienced leadership and field supervision with a broad, deployable workforce. That structure lets us scale to the size of a storm or a program without losing the oversight that keeps work safe and to standard. You get the manpower the job requires and the accountability you expect, on every project.

◆What We Stand On
Safety. Quality. Reliability. Community.

Safety
The first priority on every job. We plan the work, brief the crew, and make sure everyone goes home the way they came.

Quality
Work done correctly, to utility standards, the first time, so the system performs and the results hold up.

Reliability
When you call, we answer. We do what we say we will do, on time and within budget.

Community
Power keeps communities running. Building and restoring it is why the work matters to us.
Leadership
Experience That Runs the Job
GMB’s leadership brings more than 100 years of combined experience across utility construction and storm restoration, the kind of judgment that keeps complex, high-voltage work safe and on schedule.
