what we do

Green River sees sustainability intelligence—using data to make and justify good decisions—as the means for organizational transformation.

Every sector and industry has standards and certifications. We build metrics-driven software that identifies, prioritizes, and tracks progress to your goals—as well as using that work to improve outcomes beyond the sector.

For communities that utilize multiple HMIS installations, the In Door combines detailed client information in one web-based application. The In Door Warehouse consumes information from any number of HMIS data sources, merges and de-duplicates records, and provides an easy way to access a client's comprehensive service history, view statistics, run reports, and monitor data quality. In Door is a tool that facilitates matching individuals with housing opportunities, and supports the intra-agency communication necessary for successful move-in. As a stand-alone system, or tightly integrated within HMIS, In Door brings structure and efficiency to an often complicated process.
