Proven Solutions for Critical Systems and Infrastructure
The SDI story began in 1989 when SDI President David A. Gupta gathered together a group of talented, engineering-oriented professionals and focused their technical systems expertise to better fulfill the operational needs of clients. From a single yet complex government departmental client, SDI expanded further into the public sector, real estate, utility, education, and transportation industries. Incorporating in 1996, SDI stands as a privately-held company comprised of more than 100 business and technology professionals averaging 15 years of industry-specific experience per employee.
SDI has invested in building a technology-based consultancy that addresses the needs of owners and managers of spatially-oriented physical assets. Today, we are a force to contend with. From 911 centers to airports to commercial real estate, SDI’s professionals are trusted to keep their mission critical systems operating efficiently. SDI embodies the technical breadth, depth of talent, and complex systems experience of a national, top-tier systems integrator - with a reputation of sticking with our projects until our obligations are met and our clients are successful. For over 20 years, we’ve been there for our clients, and people are taking notice.
Continuing to build on our core competency of managing strategic assets through technology, the company, headquartered in Chicago, Illinois, now supports operations for nearly 150 clients, achieving consistent annual growth in revenues.
SDI strives to attain its mission of becoming the preeminent advisory services firm in its customer set by working within a framework of carefully selected core values:
