A group of 38 researchers, policy makers, and practitioners from seven countries, speaking nine languages and representing diverse perspectives, gathered in May 2009 in Orlando, Florida, to establish the International Network for Justice Health. The Network can assist policy makers, researchers, and practitioners to improve the health of justice-involved populations; however, achieving progress will require individual and organizational commitment to working with colleagues across different disciplines and different countries. The Network aims to facilitate this collaboration and become a focal point for the sharing and dissemination of knowledge. Its priorities will continue to evolve and to be determined by members. As a collaborative venture, the Network is only as strong as its membership. Readers are encouraged to join (membership is free) and to contribute.
