Hester Street (HST) worked with the NYU School of Medicine Department of Population Health and NYU Furman Center for Real Estate and Urban Policy on a formative needs assessment and development of an innovative Community Health Worker program to improve the health of residents of subsidized, low-income apartment buildings while advancing knowledge about the relationships between housing conditions and health and health services use. HST organized and facilitated two workshops in each of the pilot buildings in order to understand residents existing use and knowledge of health issues in their neighborhoods, buildings and homes. The results of the workshop helped inform the structure and focus of the pilot Community Health Worker program in each building. In 2017, building off prior work, HST organized and ran interactive workshops on green cleaning and integrated pest management in each of the buildings.
