We use cornerstone for work and I've been nothing but impressed over the years by Gene and Mike. Family owned and operated, honest, and they go the extra mile for their customers. Their customer service and communication are top notch, but the cherry on top is their proven commitment to their community.

I've used Cornerstone Security for two projects and have been happy each time. Employees are onsite when they say they will be and the jobs were both done in the quoted time and for the quoted costs. I will certainly use them in the future.

What a joke. You better disarm those security guards. They act like that around me. We gonna have a issue!!!
