Our history begins with a “hand shake” agreement in 1971, in which Kevin McNicholas crafted a partnership to provide programs, souvenirs, and press box catering at Denver’s Mile High Stadium.

In 1973 this company, K-M Concessions, Inc. (K-M) secured the visitor service contract at the Denver Zoo, and continues to provide these services today. These include: retail gift shops, concessions and cafeteria style service, full service catering, ride operation, and janitorial services.

In response to demand from cultural attractions around the country, Kevin formed Service Systems Associates (SSA) as a sister company to K-M, with business partner Timothy Brantley in 1989.

Following in his father’s footsteps, Sean McNicholas joined the ownership team of SSA, leading our strategic financing and growth initiatives.  SSA now serves well over 25 million visitors annually!

Our organization was built on the integrity of a hand shake. These ideals are just as important to us today as they were thirty eight years ago.
