For more than 20 years, SDI has delivered mission-critical systems and technology services to some of our nation’s most complex and public-facing organizations and government entities.
In 1989, Environmental Systems Design, Inc. (ESD), a premier engineering firm, developed an in-house support staff to design and manage information technology solutions for its engineering disciplines. In subsequent years, the information services division was sought after to provide stand-alone technology services to local governments, utility clients, and businesses in the real estate, healthcare, and finance industries. On November 22, 1996, the information services division emerged from the parent company as SDI (System Development.Integration, LLC) with a mission focused exclusively on providing superior information technology solutions and advisory services.
In October 2017, SDI acquired NexLevel Information Technology, Inc. (NexLevel), a West Coast IT management consultancy. The acquisition builds SDI’s local delivery capability throughout California while deepening its IT consulting expertise across the technology life-cycle – including planning, systems implementation, and ongoing operations.
Today, SDI is privately held and has been renamed SDI Presence LLC to reflect its commitment to being present for its clients, team, and community.
