Built on trust.
Founded 2012 in Oak Ridge, Tennessee — trusted in the country's most demanding facilities.
The Journey
2012 — Oak Ridge, TN
Trinity Contracting Services Co., LLC (TCSC) was founded as a full-service electrical contractor, beginning our work at the U.S. Department of Energy's nuclear facilities — historically known as Y-12, X-10, and K-25.
Expansion
Our experienced management team brings a level of trust, precision, and professionalism second to none. Backed by deep relationships across the general, electrical, and communications trades, TCSC's craftsmen have logged thousands of hours on complex, high-stakes projects — the kind of work most contractors simply can't take on.
Today
TCSC's combined team experience exceeds 100 years, and our commitment to quality, precision, and performance guides everything we build.
