HOLDER Security was founded in 1997 by John Holder. From the very beginning our focus has been on bringing our customers the finest security products available and supporting those products and our installations with exceptional customer care. Our business has grown from a small residential alarm company that operated out of John’s basement into a security integrator that provides Burglar Alarms, Commercial Fire Alarms, CCTV Solutions, and Card Access Systems. Over the years we have grown to service thousands of systems in Colorado and our customers appreciate our client focused approach. In addition to our own client base we also provide service, installation, and project management expertise for over 20 national companies that service national accounts but do not have offices in Colorado.
