We’ve been using GCSI for two years now at WOOF Day Care & Boarding. Always responsive to our needs along with great customer service at reasonable rates. I had another business and used Simplex and the difference in both service and $$$ is substancial. Dominque in customer service is always terrific and prompt. They’re smaller so you get that extra that is hard to find with the bigger boys.

I’ve been a customer of GCSI for the last 15 years. They are the standard by which all security companies should be judged by. From their office staff, the technicians, and even the monitoring company they contract with, everyone does an outstanding job. And they do this job for a reasonable cost, often for less then the larger, more well known companies. Sometimes I pay my bill in person at their headquarters, and when I do they can’t be any nicer. It’s obvious they truly care about their customer’s satisfaction. As long as they continue blowing away the competition, I will always be their customer.
