MDI Access

MDI Access has been recognized three times by INC Magazine as one of the fastest growing, privately held firms in the U.S. We began operations in 1992, shortly after the divestiture of the Bell System building Central Office sites for Competitive Local Exchange Carriers (CLECs). At that time, the main driver for site location was connectivity. Everyone wanted to be in the same buildings and in the same "NFL" cities. Today, data center infrastructure needs are as varied as our customers and MDI Access offers a wide variety of services to fit those needs.  

MDI Access has been providing clients with innovative, cost-effective infrastructure management and data center solutions since 1992. Located just outside of Chicago, Illinois, MDI Access has design/built and retrofitted more than 1,000,000 square feet of central office and data center space in 25 states across the U.S., Canada and Asia.

From multi-site rollouts to smaller scale deployments, our time-tested, five-step process remains the same: define, design, model, construct, commission.
