Established in 1983, SESCO began as a wire harness manufacturer serving the construction industry.  Since then we have grown to become a leading  Electrical Contract Manufacturer (ECM) providing wired devices and assemblies to a broad spectrum of markets.  Our quick response to our customer's requests, especially in time sensitive situations is the primary reason for 20+ years of continued growth. 

First received certification in 2000, SESCO is an ISO 9001:2000 company and a founding member of WHMA (Wire Harness Manufacturer's Association).

The success of any company is measured by the quality of their people.  SESCO personnel enjoy an ever challenging, and result oriented workplace that recognizes and appreciates their contributions.

The average SESCO employee has eight years of service, thoroughly trained to meet IPC/WHMA-A-620 standards and must receive certification to work in each of the departments.

In addition, every SESCO employee is trained in quality inspection and customer satisfaction.
