My wife and I are so very pleased with Kate Star at Guardian Alarm systems here in Columbus, Ohio. She is always so responsive and helpful any time I have a question or an issue that needs to be addressed. Guardian alarm as a company is a great home protection service (we've used them for the past couple of years) and I highly recommend them to you. We just renewed our 3 year contract.
