Great company to do business with and would highly recommend to anyone looking for a full service provider when it comes to Fire, Life Safety and Security. I've had the pleasure working with Eric Gray out of their Louisville branch. He's very knowledgeable, dependable and quick to respond. He's definitely an asset to the Koorsen family.
