Our Chicago Story

2021 marks the 31 year anniversary of the founding of DS (Diversified During the past 31 years, Diversified Systems has witnessed significant changes and events in the technology space. We have experienced multiple epochs in the evolution of the national and global technology industry including (but not limited to) Mainframe, distributed systems, web based, mobility, SAS, Y2K, Enterprise wide solutions, and now the Cloud. Looking ahead, the emerging world of AI will challenge us in very different and unforeseen ways. The velocity of these changes has disrupted major industries and eliminated others.

As a company, Diversified Systems has not only witnessed this change, but we have been a participant as a change agent. Diversified Systems views the future with a firm sense of informed optimism. Diversified Systems leadership has developed a vision of an integrated technology ecosystem that will radically change the way society is organized and how people utilize technology in their everyday lives.

An essential part of this strategic vision is expansion. Expansion into new technology solutions and to new geographic locations. Diversified Systems has been engaged in a gradual and strategic expansion. Chicago is a prime example of this strategy. Our Chicago office was launched in 2016. Chicago is a world class city that remains a key transportation hub and a global business center. Its diverse economy and robust education institution has placed Chicago at the forefront of Information Technology innovation.

We believe that Chicago provides us a fertile environment for Diversified Systems to leverage our 31 years of experience to add substantial values to the public and private organizations throughout the Chicagoland, State and Midwestern region.
