Mission & Vision

Social Interest Solutions (SIS) is dedicated to improving access to quality health and social services through technology and policy solutions.  SIS is a mission-driven, non-profit organization that puts the needs of our clients and the populations we serve at the center of our solutions.  Our success is measured not by our bottom line, but instead by the number of people who benefit from the solutions we develop, the professional services we provide, and the policies we influence.

The genesis of SIS dates back to 1999, with the development of Health-e-App, the first Web-based system in the U.S. to fully automate enrollment in Medicaid and the State Children’s Health Insurance Program (CHIP).  The principals involved in the development of Health-e-App and its successor, One-e-App, subsequently founded SIS to manage the ongoing development and operations of these and other innovative technology solutions.  In 2006, SIS became an independent nonprofit 501(c)(3) organization.

Over the course of its history, SIS has successfully delivered, and continues to support, online consumer-directed health and public benefit tools, including eligibility and enrollment interfaces, in Arizona, California, Florida, Indiana and Maryland. Today, SIS continues to leverage technology and business process and influence policy with the goal of connecting people with needed public and private health and social services programs.
