Tru-Amp Corporation was organized in March of 1974 as a Mississippi Corporation under the name Tru-Amp Engineering Service, Inc. In June 1980 the company bought an existing electrical service company, merging the two and changing the name to Tru-amp Corporation.

We have been providing electrical engineering services, retrofitting, testing, inspecting, cleaning, adjusting, and appraising electrical distribution systems and apparatus continuously for more than forty-five years.

Since its inception in 1974, Tru-amp’s management has concentrated all its resources toward providing quality engineering and testing services to its customers. Management has and will continue to broaden the scope of services through employee training and utilization of state-of-the-art equipment and techniques. Employees continuing education is through on the job training, seminars, and webinars in order to provide our customers the most current technology available.

Proudly Serving the Southeastern US

Tru-amp’s service area is primarily the Southeastern United States. We have, to date, performed electrical testing and inspection services in twenty-six states.

Tru-amp’s affiliation with the telecommunications industry began in January of 1981 when a long-term contract for switchgear maintenance was established in Louisiana. In March of 1981, Tru-amp began a similar switchgear maintenance program in Mississippi. A contract was added for Alabama in 1984. Contracts for switchgear maintenance of telecommunications facilities through the southern and eastern localities were added the same year. Those contracts have expanded each year to include such major communication centers as Baton Rouge, Louisiana, Dallas and Houston, Texas, Memphis, Tennessee, Birmingham and Montgomery, Alabama and Pensacola, Florida. The maintenance contracts have continued since they were first established.

In addition to Telecommunications Industry, we have steadily added to our customer base of Industrial clients. For our Industrial clients we provide annual testing, maintenance, and infrared scanning, as well as troubleshooting and repair services. Many Hospitals, Federal buildings, and United States postal facilities have used our services over the years.

We have been very successful in our ability to provide quality service to customers with a large number of facilities and to establish and maintain databases for those customers.
