SSC Client Login


SMG Corporate Services is a fourth-generation family-owned business that started modestly as a window washing company in 1924. From the start, the belief was that growth would come by delivering the best value exchange — that, in exchange for the opportunity to provide services to a client, the team would be obligated to uncover and solve any type of facilities-related issue. In this belief, the concept of providing Reliability At Every Level was born.

Over the decades, SMG Corporate Services has grown and evolved in response to the varied needs of clients. Today, SMG Corporate Services operates as two aligned companies – with SSC providing Security, Training, Background Screening and Investigations services; and SMG providing Cleaning, Janitorial and Property Maintenance services.

And the story, as they say, goes on.
