What I'm looking for
At McKinstry, I lead low-voltage construction projects from preconstruction through commissioning, owner turnover, and closeout. I manage project financial controls and coordinate field crews and subcontractors across structured cabling, fiber optics, CCTV, access control, audiovisual, and life-safety systems.
Earlier, I led operations and multi-project field execution at Cascade ElectriComm / Rainier ElectriComm, and managed data center wiring installations at Advanced Classroom Technologies, including work at the Microsoft data center in San Antonio, Texas. My experience also includes underground and aerial fiber construction, commercial and residential projects, and hands-on low-voltage installation.
