Evergreen System Modernization Project

The Evergreen System Modernization Project is an OADS initiative to build a single system to replace EIS, MAPSIS, and MECARE. Evergreen Data System (Evergreen) is the name of the new client data system for Developmental Services, Adult Protective Services and Long-Term Care.
