In 1972, GLESSNER Alarm & Communications began in the basement of the Glessner's home. From the start, the family focused on the grass roots approach of exceeding expectations, personalized accessibility with total commitment to service. Today, these same ideas continue to be the company's hallmark. As a family-owned business, we take great personal pride in what our company has accomplished. But, we never forget our humble beginnings and the philosophy that has made Glessner a company that thousands of customers and business have come to rely on for their security and communication system needs.
