We are a large industrial facility with 350+ extinguishers, wheeled units, halon systems, sprinkler systems and foam systems. Doug does a fantastic job for us. I could not ask for a more knowledgable, helpful or dependable service tech. If I call Doug at 2 am, I know he will be here. Doug never drops a problem in my lap without a soulution in mind and his solutions are always the most cost effective. He is our go-to guy for fire suppression!
