dsi’s roots are in Chicago. Hogan is a product of the Chicago Public Schools and obtained a graduate degree from Northwestern University, one of the finest institutions of higher learning in the United States, located in Chicago.
As such, dsi’s earliest projects were for Cook County (Illinois) and the City of Chicago. Very early in dsi’s history, the Chicago Public Schools undertook the largest school Capital Improvement Program in the United States. dsi was key to integrating and delivering that multiple project effort. As recently as 2014, dsi has worked in public schools in Chicago.
We continue to provide services to the local counties, as well.
