See what our clients have to say about our work


The support provided by Defiance Electric in the recent Lebanon College project was excellent despite challenging site conditions and tight funding. The Defiance team consistently addressed issues before they became problems, planned time efficiently, produced high quality work, value engineered the project to create a high return on limited funds, and put forth the extra effort to coordinate power feed problems with the city to eliminate potential power concerns in the future. Jay and his team were a pleasure to work with, and because the design and installation of the entire project was managed by one team, many potential problems were avoided.

It’s extremely rare to find a single company that possesses the electrical and data communications expertise that today’s data center solutions require. Defiance and Crossover have proposed, designed and implemented professional data center solutions within the U.S. and Europe, exceeding expectations and meeting extremely aggressive deadlines.
— Wayne St. Jaques, Tele Atlas
Defiance Electric has been a professional, helpful, and thorough Siemon Certified Installer. I was showing off pictures from our most recent project—and it is beautiful art! Defiance Electric and Crossover will always be our first and last call for any cabling opportunities.
— Christina Marrone, Siemon Company
