DIS International Information Systems, Ltd. began life in Michigan in 1982 as a joint venture in the insurance and software industries between Mark and Stephen Klein. In 1987, the insurance arm was sold and the software arm was reincorporated in California.

DIS International has specialized in systems level software consulting revolving around kernel and database internals. We have also performed application consulting and implementation services over the years. Most recently, we've been involved in the Real Estate community working with the Real Estate Transaction Standard.
