Voltrio love
“Voltrio is good at keeping technical expertise in house, which I find very valuable with an automation distributor. You’re running into things that you’re not sure about. Bob Lawler came up and helped us out and even provided a little bit of training on some of the modules that we use. That’s probably their biggest strength.”
