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 of prior work, HST organized and ran interactive workshops on green cleaning and integrated pest management in each of the buildings.
