In 1972, GLESSNER Alarm & Communications started in the basement of the Glessner's home. From the start, the family concentrated on the grass roots approach of exceeding expectations, personalized accessibility with total dedication to service. Today, these same ideas continue to be the firm's hallmark. As a family-owned business, we take great individual pride in what our firm has accomplished.
