About Us

Tri-Electronics was founded in 1963 as an autonomous division of a large electrical contractor (Tri-City Electric). Its initial mission was to provide that contractor with an entree into the institutional intercom markets. Tri-Electronics has been designing, building, and supporting high-performance work and technology environments for our customers throughout the United States. Our ‘services first’ approach, along with our investment in the very best talent and infrastructure to support our work, has helped us become one of the most respected audio, visual, security, and communication solutions and services firms in the industry.
