About SDSI

SDSI has operated as a CDDO only since 1999 and does not provide direct services to individuals. SDSI is currently the only private not-for-profit, multi-county CDDO that does not provide direct services in the state of Kansas. SDSI is one of only 5 out of 27 CDDOs in the state that does not provide direct services.

The SDSI governing board

As a CDDO only, our governing board does not have a conflict of interest in the decision-making process as it might have if SDSI was also a service provider.

The SDSI Board of Directors is comprised of one representative from each of the counties in our service area. Their respective county commission recommends each of these representatives.

The SDSI Board of Directors is totally independent of all service providers in the area.
