Our Team

We’re committed to offering our customers creative, common-sense approaches to installation, repair, and periodic service of your building or facility's systems. 


Our skilled, learned, and motivated technicians understand our customers’ concerns regarding reliable and trustworthy equipment. Although life safety is of the upmost concern, we respect the fact that property, inventory, data, and even production can be just as precious. This critical understanding is what sets NJSTI above the competition.
