Apollo International

The story of Apollo International begins in the most unlikely of places – Vietnam in the 1960s. Dennis Crowley and Richard “Dick” Ryer met while on duty in DaNang. When Dennis’ tour ended in 1966, he and Dick pledged to do something together in the future. Twenty-four years later, they did. Dennis and Dick founded Apollo Security in 1990 in Dennis’ Massachusetts home with the help of Dennis Crowley, III, known as Denny. It is engrained throughout Apollo to immediately respond to clients’ needs, and when necessary, “go to the point of the flame.” As the company expanded domestically, the team began taking on more and more international assignments, taking advantage of its senior management’s global expertise. In 2012, after 22 years as “Apollo Security,” the company changed its name to “Apollo International” to reflect the company’s increasing global reach and sophistication. Apollo International has headquarters in Massachusetts and New York, with support offices in New Hampshire, Pennsylvania, Maryland, Tennessee, Virginia, Minnesota and Indiana. We provide security services nationally and internationally with the help of strategic partnerships and regional, in-market security agents. Our experienced leaders ensure all clients have access to our personalized security expertise no matter what the situation, where the security need exists or when it is required.
