Welcome! is the online home of the HN2 development team.

HN2 is a public health, clinical data system. It is an open-source (GPL), web-based application built on the LAMP platform.

Current projects include: HN2 and supporting systems such as Medbill, HNTracker, Data Submission Systems (mhar, family planning, revmax, wic, vpod, grits.)
