Our Story

Our story begins in 1984 when Steven Schallert, owner, and President, saw a need for high-quality custom programming services in the Effingham area. As System Development Services (SDS) grew, our focus expanded to include IT services. The company incorporated as System Development Services, Inc. in 1996. SDS has continued to grow by acquiring several area computer companies. These acquisitions have allowed us to expand and offer the best technology services from highly qualified professionals in the area.

SDS is known for our technological expertise, prompt service, and innovation. Since our beginning, we have aggressively invested in our customers' technology needs providing training, and the most up-to-date hardware and equipment upgrades. We maintain partner relationships with leading vendors such as IBM, Microsoft, SonicWall, Cisco, 8x8, HP, Dell, and others. These partnerships require us to maintain advanced certification levels which help us to keep on the leading edge of the technology curve.

We are here to help your business with your technology needs.
