North American Alarm Co. traces it's history back to 1968, when the son of a security company owner opened an alarm operation. In 1972, Bill Cereske, the current President, formed his own fledgling alarm enterprise. By 1975, the two companies had merged to form North American Alarm Co. Soon thereafter the Son from the security company owner sold his share to Bill, who has led the firm ever since. From humble beginnings, North American is now a leader in the local security industry. Bill is still friends with both Father and Son to this day.
